I bought two 30 pack discs of Memorex DVD-R. It was absolutely disappointing. I thought that because it is a Memorex brand that I got me reliable discs, it did noit turn out that way. of the total 60 discs about 20 discs were defective! That's 33% failure rate! while recording on Memorex DVD-R discs, I will suddenly get an on-screen message like: Recording failed. And that will make the entire discs unreadable anymore. Other brands, like WinData have better quality and very, very low failure rate about one or two discs out of a 50 disc package.

That's Memosux for you.Stick to brand name media such as Made In Japan Sony and Verbatims.They are the best and will hardly or ever fail you.

That's still a high coaster rate for my standards.
I AVG 1 coaster out of 400+ backups with media like Taiyo Yuden,Verbatim, Ritek,Hitachi maxell,and sony.And that usual culprit of my occasional coaster is a factory flaw.
Lots of cmags in those memosux,as well as Moser Bauer- MBI. Low quality dye,uneven dye,and blemishes.
With those burn coasters,your dma's thrown into pio. When you get 5/6 burn errors in a row,windows will revert the DMA's into pio mode for safety purposes. That can also screw you up.
What's the brand name and model # of your DVD-RW drive ArnoldZ?
Can you locate the current firmware version for that drive?
Use nero's infotool,dvdidentifier,or dvdinfopro to find that info.
What programs you using in the dvd backup process: Ripper/compressor/burn engine?
Certain drives will favor a certain format. Example: Benq's highly favor the plus.
A firmware update may help you out.It controls the writing strategy,especially on older burners being able to handle the faster 16x media.The firmware tells your burner how to properly burn the discs you throw at it.
Burner quality also a factor. There's some crappy drives out there. My coaster percentage with my HP 640C LS burner is about 20% and that's with taiyo yuden and maxell hitachi media.A total pc of crap burning drive,but ok reader and lightscribe drive.

Thanks for your info.
I prefer not to mention the brand name of my DVD recorder. Since the failure of the Memorex DVD discs is not a function of the recorder. Other brand discs (low priced, virtually unkonown brands), do great in the DVD recorder, it's just the Memorex brand that have such a disgustingly intolerable high failure rate.
The tech support group of my DVD recorder were very accomodating enough to send me a disc copy of their firmware since I do not have the software that will download firmware format.
I also agree with you that certain DVD recorders (multi-format ones that accomodates both + and -) tend to favor one kind of format. Using + format DVD discs in one of my recorders have better firmware. The + format has a different recording program - it has thumbnail images that can be selected from a recorded chapter, so I am mot limited to just the image at the beginning of the chapter. If I use a - format in that same DVD recorder, the chapter listings are just that, a listing, no thumbnail images.
One complain that I have is that all DVD recorders allow me to put title on chapters with up to 30 or so characters and yet after finalizing, only 18 characters are allowed to show. And even the info display funtion that works in the unfinalized version to show all of the 30-char title, do not work on the finalized version. Bummer!

The high failure rate DOES indicate that the failures are due to a function of the recorder. If the recorder's firmware does not include the MID code for the discs, then it uses the default write strategy which may or may not work. If that is the case, it is not a quality issue of either the recorder or the media--you can't judge the quality until the two are compatible. The firmware update may or may not make the recorder compatible. It will make the media compatible only if the MID code of those discs is included in the firmware update.
If media with the same MID code work while others with that identical code do not, then there may be an issue with consistency; and that is a quality issue. But I suspect that all discs with that particular MID do not work because of incompatibility. A firmware update and a switch to more compatible discs such as Taiyo Yuden or Verbatim that almost always work is often taken as "proof" that one incompatible brand or another is garbage; but in many cases the firmware update took care of the problem--the user just never went back to check. One can only draw a valid conclusion when all the variables have been eliminated.
The +R/+RW format design is for both data and for video, unlike the -R/-RW format that was intended only for video with fixed sequential recording, even for the rewritable -RW. (DVD-RAM was reserved for data in the original plan.) HP, Philips, and Sony split from the DVD Forum because of the limitations of the -R/RW and -RAM system, and perhaps because they would share the royalties on Philips's "lossless linking" system used in +R/+RW. That's the reason why you can get multiple thumbnails for +R/+RW. It's just easier to program because of its design.

My post isn't -R disc related, but DVD Recorder related. For my Panasonic DVD recorder i use DVD-RW discs from two companies that i would not ever use again for write-once recordings, Imation & TDK. I don't know what MID codes they are yet as i've had no problems with most of them so far (so haven't had the need to check the MID codes), they're just used for recording TV programs each day and re-used.
edit- out of curiousity i checked the MID codes -
Imation 4x - OPTODISCW004
TDK 4x - TDK601saku
they even play in standalone players well too, but i hasten to add, i will no longer use write-once discs from Imation, TDK or Memorex, too many problems in my experience

Quoting myself,(in bold type below). actually it is with the + (plus)format where the unit provides thumbnail images and the -(minus) format is where itemized listing is allowed.
(Note: in the first statement below the hyphen is just to point out that the + plus format has thumbnail images. Sorry if that hypen was mistakenly taken to represent a -(minus) format)
The + format has a different recording program - it has thumbnail images that can be selected from a recorded chapter, so I am mot limited to just the image at the beginning of the chapter. If I use a - format in that same DVD recorder, the chapter listings are just that, a listing, no thumbnail images.

I know everyone says that Memorex sucks and I used to think that also and for a long time would not buy them, then one day I got some off a clearance rack at an office max and they worked great. So I bought a 50 stack, great flawless burns again. So last Christmas I bought two 100 stacks at two different stores a couple weeks apart and have only had one bad disk and I am almost finished with the last stack. One bad disk in over 300 burns. So much for "sucks" just bought three 50 packs on sale.

Not everyone says that Memorex sucks. There are actually a few people who know a thing or two about media and realize that consistently bad recordings is more likely a function of compatibility than quality. Another thing to note is that anti-CMC posters tend to congregate on this website while those satisfied with CMC products congregate on other websites. (I just read one response to the question, "Why do you hate Memorex?" The answer, "I just repeat what everyone else says."

This exactly describes my first (and last) experience with Memorex nearly 3 years ago now. I had total success with my first packs and so I ordered a load more. Not one of the second batch would burn. They had the same MID codes. I could take one from the old pile and burn it, followed by one from the new pile and it failed. I repeated this process a number of times. I guess this really was a quality issue.
