Xvid or DivX media corruption resistance.

[Dologan]

Hello,
I am thinking about burning my DivX and Xvid files on CD-Rs. I would like to know how resistant the formats are to media corruption, that is; will my movies stop playing if some sectors get damaged? Unfortunately, I happened to buy a tower of not-so-good quality CD-Rs, and I am afraid the movies might become unwatchable if one of those CD-Rs deteriorates too quickly. I don't mind if a few frames suddenly distort, if I want quality I'll go right to the DVD.
Thank you.

That's the job of the container and the filesystem.

I.e. it has got nothing to do with the codec, it depends on the container that you use (ogm has some error-restance) - but most of all you don't have to worry about it as there are multiple levels of error recognition and recovery on CD- and DVD-Rs performed by Reed-Solomon code which you don't realize (and don't need to). ;)

Well, it is more the CD format/burning speed than the container format (I would say 75% CD format, 24% burning speed and 1% container format).

Burn your CDs at a lower speed and all should be fine.

As for CD-Rs: burning them at 52x will certainly cause problems, anything below 48x should be fine. And it would seem good idea no to use un-labeled no-name CD-Rs from the supermarket. Brand-names don't mean that much, but most brands (in Europe) actually use RITEK-CD-Rs which have improved very, very much in the recent years.

Actually there should be no big difference between 52x and 48x
It is known that: higher burning speed = more burn errors
So you can't just say everything below 48x is fine. Many 48x certified CDs burned at 48x have too many burn errors.
If he has the time, why not burn in 12x or 16x ;)

Thank you both for your prompt replies.
While I am a newbie at video coding, I have some experience in audio coding and I had thought that, since some audio formats do have different hardiness to corruption (i.e. FLAC vs Monkey's Audio), I reckoned it might have been the same with video.
Regarding the burning speed, I am well aware that high speeds, regardless of the media, tend to introduce more errors, so no, I didn't plan on burning at 52x, 48x nor 24x for that matter. Actually the computer I have the files on only has a 8x burner installed and I am too lazy to transfer many gigs to another one. Besides, I've got time. :-)
As for the CD format, which apparently is so important, what do you mean by that? In case it's something I have some control on, what is the best one?
Thx.

Perhaps you'll find this article worth reading:

Well, by CD format, I ment wether mode1 or mode2/xa.
As you're burning divx files, you better burn in mode1 (700MB on an 80min CD-R). Because this mode has a much stonger error recovery capability than mode2/xa used on VCD and SVCD. So I highly recommend you to avoid any type of tricks that can burn avi files on mode2/xa, allowing for 800MB on 80-min CD-Rs, because the error correction is very bad in this mode. I'm getting already enough burn errors in mode1 ;)
