Burning speed, does it matter?

[jedi]

hi guys, i have the tcf screener of super troopers, and when i play the .mpg off my hard drive the file is fine. No sync problems at all. then i take the same file burn it to a cd-r at 10x. put it in my DVD player and the everything is fine, but 10-15 minutes into the movie the Audio is not in sync by like 2-4 seconds.

what was the cause of this problem? is it because i burned it at a wrong speed? all advice is appreciated.

and i read the HOW TO's, but i wanted to see if any of you had any other ideas of what to do. man to tell u the truth i really dont understand the guide that well. pls all help is appreciated.

no burning speed souldnt matter. sometimes when the movie is being encoded, the audio or video file runs faster/slower (could be either one) so they fall out of sync. only solution ive found to that (when your ripping a dvd) is to decoed the audio ac3 file instead of encoding it into mp3 or wav. thats all i know...

I usually burn at 12x or lower for VCDs even though I have a 40x burner. What I have found is my Pioneer standalone will play the VCDs burned at 40x but my portable VCD player has problems with the same VCDs. Then I found that when I burned the same video at a slower speed my VCD player had no problem. I don't know the details of the higher speed burners but the data tracks on a CD burned at 40x and one burned at 12x look very different. Maybe someone else could elaborate.

so is the only way to fix it, is the gradual audio guide here? someone else told me to mux and re-mux or something like that. would that work?


the thing is i didnt rip this video, i got it from irc. so what can i do about the ac3 thing? also i didnt encode this at all. the mpg file on my HARD DRIVE works fine no problems at all. when i burn it on a cd-r to watch on a DVD player, thats when the problem starts happening.

well you cant do anything about the audio since you downloaded it (the ac3 audio) so that ideas out.

i dont know what else to say, you could try burning at sloer speeds and see if it helps. did you play the file on you pc? is the audio in sync when you view it on your pc?

have you checked the region code on the mpeg file it could be encoded with pal and you burned it as ntsc that could cause playback problems but normally the video skips if that happens. you may have to extract the audio out of the file and convert it to wav with virtual dub or mp2 using TMPGenc. or you might want to decode the ac3 file to mpa then re-encode it back to ac3 using 44100khz instead of 48000khz.

I burn all my disks at 40speed and have no sync problems on group released mpg's through IRC

However I did convert D-Tox from AVI to mpg myself and whilst it played fine in a Sony standalone the audio went out of sync on my own Dansai standalone.

I conclude speed of burning makes no difference. Rather media and brand of standalone may affect performance

well i played the file off my Hard drive and it worked fine. i took the same file burned it to a cd-r then thats when the audio problems happenened.

my friends player doesnt support SVCD so i encoded it back to mpeg1. then i took the mpeg1 disc, tried it out, and still the same problem at the same part in the movie. so what else can i do?

[jedi]

would de-muxing and remuxing help?

anyone?any ideas pls?
