MPG Problem

[BigBadBob]

i record a lot of tv shows and am gettign some problems. One cd i recorded about a month ago with an episode of Star Trek - TNG. I copied the file to my hardd rive to watcth it. ( i dont do VCD anymore ). the second half hour i noticed some wierd thing happening. there are multicolored blocks over the whole video area, some popping noise and sometimes some locking up. i think that cd and 150 others are Ritek unbranded cds. or that's what they were sold as. i am thinking it could be a problem with Windows Media Player, possibly need a new version, or wrong setting in NERO ( ISO 9660, ASCII, Joliet, those things) or maybe jsut bad quality cds. I am no longer going to buy cheaper cds, going to stick with Memorex, or Fuji. Have several spindles recorded and no porblems. Any ideas will be great. I dont want to continue getting problems like this. I just threw put 150 bad SMart Buy branded cds because they wouldnt even be recognized in my CD-Rom drive.

I have gotten similar effects with a particular brand of CD-RW (lots of block noise and play-back freezing). If I burn to a different brand then same VCDs all is fine.

In other threads some people have mentioned burning at a lower speed to lessen errors in the writing process. Remember VCD/SVCD format CD's (Mode 2 ISO) have considerably less error handling and correction built in so data errors are much more common. Try you CDs again but burn at a lower speed (maybe 4x as mentioned in other threads).

Otherwise as you say user other brand CD's

i have 24x Acer cd-rw drive. i usually burn at 20x. here are my pc specs and cd recording settings i use.

PC:
Athlon600
D740X 40gb
ATI AIW Radeon 7500
DVD-Rom
Acer 24x CD-Rw
Linksys NIC
SB Sound card

NERO:
ISO Level 2 (Max. of 31 chars )
Mode 1
ISO 9660
Joliet
both boxes checked in ISO restrictions box.

i am not too familiar with what these settings mean. But i record a lot of cds ( sometimes as many as 10 per day, but usually about 6 or 7 ) so i really dont want to go back to the 4x speed as i had before i got the new cd-rw drive. i could probably go down to 16x. Also could it possibly be that the processor is too slow, i am planning on getting a new mobo.cpu but dont have the money right now. or maybe limiting the file size to 100mb per file, there would be more files but smaller. I also read on another site that some problems can be linked to dirty laser heads. Could this possibly help. I have recorded about 200 cds and played 100 or so others plus played a lot of games.

i figured out how to copy to my hard drive and play it without those problems. I went to the Digital Video Forum forum.digital-digest.com and found a program called ISOBuster. i extracted the mpg file with it and the file played with the problems i described. i am still going to try to find a way to prevent it from happening, but this seems to work. (For now ).

I do not think it is related to your PC. If your PC was too slow then you would get failure in the burn process. Mainly this would be caused by slow hard disk access.

Your problem is caused by write errors during the burn process corrupting the mpeg files on the CD. The best solution is better CD media.

It is most likely the media cannot handle being written to at the speeds to wish. I have never had this problem (only 12x drive for me). Other forums have talked about the problem.

Otherwise I hope you resolve your difficulty.

PS VCD/SVCD are Mode 2 CDs so I gather your CDs are not that type as listed in your previous post.
