What program is available to test the quality of a burn? I was using Nero CD DVD Speed's scandisc but I would like something that allows you to identify the area of imperfection so that you can dial it in on your dvd player (find the chapter where the error is ) and see if it is noticable. I thought that I remembered being able to do this on the scandisc but I cant seem to get the ihfo I need.
Thanks,

Try Nero CD-DVD Speed's 'Transfer Rate' test. If you have more than one burner/reader try it in both. A nice clean line will usually guarantee success and helps determine if you have a good media to burner match.
Here's an example of a bad media/burner match, although it still might play.
Here's an example of the "my movie glitches/breaksup/ stops at the end" (a very common complaint). If you must use discs like this set your software to not fill the blank, ie use 4GB instead of 4.3GB.

Thanks.
I found a tutorial for Nero CD DVD Speed that was rather useful for a rookie.
I am getting some interesting results. This is one of the discs that failed varification (plays fine but has a slight freeze at the layer break. What is your take on this?

Here is what I believe to be a good burn that I made. Do you agree that it looks good? In an ideal world should it not have the little small spikes? Are the spikes of that size of any significance?

what you need to do is try a more reliable test - a CRC scan ie to check for corruption, it's another tab in the same tool
edit- Nero's verification is not very good at all

i'm in Linux at the moment so am going from memory, i think it's the disc scan or something like that; it's basically on the screen where there's loads of tiny squares in a grid, and when the CRC scan runs it changes the squares to green, provided there's no corruption..

Yep, it's ScanDisc, next to "Disc Quality".
GREEN = good
YELLOW = damaged
RED = bad

ps the main method i use for checking burn quality is via recopying from the backups sometimes, and by watching the movies too (frequently). In the very rare occasions i ever have a disc that skips/freezes on playback, or craps out while recopying (i do most recopying via windows explorer's copy/paste of the video_ts folder and burning via Nero 6.6) i would do a CRC scan. I don't subscribe to the 'quality scans' method of proving/disproving discs are any good, just good old non-corruption or heaven forbid, corruption.

I agree with creaky. In addition, another good rule is to always use "1st class media" like genuine Taiyo Yuden, Verbatim or Maxell (Made In Japan by Hitachi Corp.) Nearly half of the SONY & FUJI 8X DVD+R (Made In Japan) are likely to be Taiyo Yuden, but it's quite hard to find them nowadays.

Doh!, i forgot to mention the obvious, i only use top notch media also (as per my sig), which pretty much negates the need for regular disc checking anyway...

Fuji DLs are on sale at a store in my area, you feel pretty comfortable with them? Who makes Phillips DLs?

That's about as good as it gets. The burner had absolutely no problem reading the disc. The firmware's write strategy was spot on. Whatever media you used your burner likes. I'd stick with it.
The Scan disc test is not important to me. It doesn't tell me if the media is a good match for my burner. Many terrible (very jagged) Transfer Rate tested discs will pass the Scan Disc test. Testing the disc's surface is not an indication of burn quality.

That is what I thought, but I had 10 consecutive bad burns that showed like this with the same media. I am at a total loss:

- that's your opinion. Pretty graphs are all well and good but knowing whether there's actual corruption is very important. Hopefully there is never any corruption but that can be avoided by using good media. If you choose to use lots of different cheapy media then various tests do become very important. I no longer take the chance on iffy media just to save a few pounds as it can be hundreds of poor discs before problems are found. But everyone to their own, i just think it's not good advice to totally disregard corruption testing. As i say, i don't advocate CRC scans often, just when a problem is found, CRC scanning then might help pinpoint a problem.

Creeky, FYI, I did not say this MysticE did. I appreciate everyones insight. From there of course I will make my own decisions.
although you prefer the scandisc what do you make of the last "pretty graph" that I posted? What is the reason for the flat line at the layer break?
Quite honestly I am being cheap and just cant bring myself to pay $3 a disc (Canadian) for the Verbatims....but when you have 10 bad burns with cheaper stuff that starts getting expensive too. It is just kind of screwed up becuase prior to this I have had very few bad burns.
Thanks,
