I just started backing up DVD's. I've created about 40 copies. I use a Sony DVD Burner (External) Model: DRX-840U with Memorex Media (they inexpensive stuff).
I use DVDFab, Shrink, and ImgBurn to create them.
I play them in my Xbox 360 and they play great. I have tried some of them in my DVD player also and they seem to play well.
I let someone use a copy of my "Get Smart" and they said it was slow in some parts and wanted to freeze in others.
Another one "Step Brothers" I loaned to a friend and he had the same issue playing it on his PC.
I don't have any problems with these myself. Any ideas?
Thanks so much.

First off...Memorex blank media is certainly not the best stuff out there. Rather, it's bottom of the barell. Use good blank media, Taiyo Yuden, Verbatim, and Sony.
Secondly is blank media format. Are you using +R's or -R's? -R's are typically widely accepted by standalone players. +R's should be booktyped for best overall compatibility.
Finally, make sure you're not burning too fast, especially with those Memorex. Burn at 6x to 8x max, with no multitasking.

I concur about the Memorex blank discs.
The xbox 360 is pretty good at playing all brands of dvd media, but not all dvd players are created equal. Some may not play dvd-r... some may not play certain brands of dvds... some may play certain brands at 2x and 4x, but not like 8x and 16x media.

I'm far from being an expert but will agree that Memorex are not good discs to be using.
Some assembly required.

Thanks for the feedback. I am using DVD-R.
I burn them at 4x. I have only had one coaster and it was my fault.

Try the +R format and booktype to DVD-ROM for best compatibility. And just so you're aware, cheap media typically deterioates more rapidly than the higher quality media. I've got some old Memorex that still play, and i've got some that don't. *shrugs* I'll still advocate using high quality blank media for best overall results. ;)

If you loaned them your originals, then they wouldn't have any problems.....

Let me borrow your originals and I will let them borrow those. Or, I could just give them your number. :)

Try burning at a more reasonable speed. Modern burners and media are not optimized for such ancient speeds. Here's a nice example of what can happen when quality 16X (TY) media was burned at various speeds.
SONY DVD-R 16X ( TYG03 )
Batch #GH000073 - 0909
LG GH22NP20 1.00 ...Nero CD/DVD Speed 4.7.7.15
Burn Speed 4X
Nice Quality score :)
SONY DVD-R 16X ( TYG03 )
Batch #GH000073 - 0909
LG GH22NP20 1.00 ...Nero CD/DVD Speed 4.7.7.15
Burn Speed 8X
A little better I'd say.
SONY DVD-R 16X ( TYG03 )
Batch #GH000073 - 0909
LG GH22NP20 1.00 ...Nero CD/DVD Speed 4.7.7.15
Burn Speed 12X
Hmm... better yet at 12X.

Then again, I don't make copies to give to my friends.....They can buy the DVD and make their own backups if they so desire, or rent the movies.

Your scans aren't showing up on my browser. Of course, at work i'm stuck with IE. So, i'm not sure if it's just me or not.

I just tried IE and just red X's. Seems odd.
They are png's.
Here's a direct link to the posting.

The quality score at 4X = 0 (zero)
at 8X = 95
at 12X = 96

I'm using a USB external burner on a laptop. Dual core, 2GB Ram, 80GB HD.
What speed would you suggest I try?
Thanks
Bilbo: Let's just say I was doing my friends a favor and backing their DVD's as a free service. I viewed them for quality assurance only. I did not receive any viewing pleasure from the experience. They were having trouble viewing the backup so I posted the issue here (a place for friends to chat). Is that more politically correct? Also, they were not copyrighted material. "Get Smart" was a video recording of me giving a lesson on internet forum etiquette and "Step Brothers" was a family video. :) "That's all I have to say about that". :)

I addressed this in my first response, but we'll go again.
The general rule of thumb is to burn at half the rated speed of the disc or 6X to 8X. As MysticE's scan shows, you can burn as fast as 12X with some pretty good results. Burning too slow can be as bad if not worse than burning too fast. However, i wouldn't try to burn at 12X with a batch of Memorex's, but that's just me.

Yesa masta, i sorry masta.
I wanted to provide information about the system that I was burning from.
Using a laptop and USB can be limiting.
Just wanted to check.
Thanks.

Seems Memorex is always the culprit, usually referring to CMC and sometimes Ritek. Yet Memorex/CMC/Ritek are the largest producers of blank DVDs and CDs with over 60% of the market. Can burner manufacturers ignore Memorex/CMC? It is also interesting to note that research has shown that most consumers burn at 'Max' speed.
One only has to read customer comments on Memorex discs to see that overwhelmingly folks like them. Are all these folks morons?

No offense but "The general rule of thumb is to burn at half the rated speed" is not based on any real world testing. Many times I read of folks who burn at 4X, because "they want a quality burn, and slow is better". Hardly, as my first post clearly showed.
Many of the reviews at CDFreaks show excellent results with CMC burned at it's rated speed, and some burners can burn over rated speed with great results. Looking at a review for the same LG we see:
Here again the LG GH22LP20 writes to this Philips media with very good results.

No those were very good results.
These days it's very easy to determine what to burn, in what, and how fast. Pick a burner that CDFeaks has reviewed and note the disc quality scans and speeds. Their forums are also littered with scans. A good general rule of thumb is to simply investigate your burner/disc options and buy accordingly.
I chose my Pioneer 115D based on it's handling of my discs of choice, 8X TYG02's.
Here's 2 scans (scanned in my BenQ) of discs burned at 12X
All it took was a little research to find a nearly perfect burner/media/speed match.

If you're meaning the scans like MysticE is posting, use Nero cd/dvd Speed.
@MysticE
It has not escaped my attention that you seemingly enjoy starting a good debate. I was expecting a rebuttal of some kind. I however am not in any mood to entertain you with a debate at this point. I'll just leave it at this: everyone is entitled to their opinions.

This is a quote from Wikipedia on CMC Magnetics.
Quote:
According to online media enthusiast communities, CMC Magnetics is reputed to be one of the worst manufacturers of CD and DVD media on the market.[1] CMC Magnetics manufactures mostly "value" media according to digitalFAQ, their reputation for quality is almost universally low and the media is not recommended if durability or reliability is a concern. [2] Many Quality/Stress scans by commercial software like Nero CD-DVD Speed reveal the media to be among the worst performing[3][4], showing extremely unpredictable jitter and many CRC errors.
Some assembly required.

CMC manufactures Verbatim DVD+/-R media as well as their CD-R media. Verbatim media are excellent quality. I know several college professors who take points off any papers written with citations from Wikipedia because of the misplaced credence given to such anecdotal information, and this is an example of the way reports can be confused with facts when readers do not know the difference between the two.
As for digitalFAQ, half of what is written there is correct. The other half is either wrong, misleading, or simply bizarre. Optical engineers read their information for a good laugh.

"According to online media enthusiast communities, CMC Magnetics is reputed to be one of the worst manufacturers of CD and DVD media on the market.[1] CMC Magnetics manufactures mostly "value" media according to digitalFAQ, their reputation for quality is almost universally low and the media is not recommended if durability or reliability is a concern. [2] Many Quality/Stress scans by commercial software like Nero CD-DVD Speed reveal the media to be among the worst performing[3][4], showing extremely unpredictable jitter and many CRC errors."
1) Some online media enthusiast communities disparage CMC Magnetics products. Other similar communities do not. "Reputed to be" used without quantitative numbers is a questionable charge. At one time the world was reputed to be flat. Increasing the number of people who believed that did not make it any more true.
2) As I mentioned, digitalFAQ has so much questionable information that it is of little value as a citation. Wikipedia, even with peer reviews, is not considered an entirely reliable source of information either. CMC does not manufacture "value" media any more or less than any other manufacturer. Price pressure affects all. CMC does seem willing to dump B-grade or even C-grade material on the market when customers request the lowest price possible without regard to quality. Spin-X is probable a good example of that, and there is an interesting story behind that decision. The blame there belongs as much or more to the brand that decided to put such stuff in the market. (Kodak and Mitsui were two companies that refused to let B-grade leave the factory. Neither manufactures discs any longer because that approach toward quality is expensive.)
3) "Reputation for quality" being universally low is contradicted by Mitsubishi Chemicals' decision to have CMC manufacture the Verbatim brand. Philips, the pioner of optical media and publisher of the disc book standards, also relies on CMC for their products. So does HP. I suspect that the optical engineers at those companies have at least as much knowledge about true quality standards as online enthusiasts. I know they have much better test equipment.
4) The best work done on long-term reliability of CD-R and DVD+/-R media under the most stringent standards found that CD-Rs would last 120 years under good conditions and DVD+R media would last over 40 years. Most of the discs in the test were off-the-shelf CMC production. (Taiyo Yuden CD-Rs, by the way, will not last as long as the CMC discs, not because of any quality difference, but simply because the dye they use is less stable than the phthalocyanine dye used by CMC and most other CD-R producers. So much for "not recommended if durability or reliability is a concern."
5) Commercial scanning software displays how well or poorly a drive reads data coming from a disc. That involves: a) the reading drive; b) the software itself; c) the recording software; d) the recording drive; e) the quality of the recording; f) the condition of the disc being read; g) the initial quality of the disc; h) the compatibility of the recording drive firmware and the disc to be recorded. Such software alone cannot reveal enough information about the initial disc quality unless all the other factors are eliminated as contributors.
