out of sync

[agent222]

I've noticed that when I convert, and, burn more than one xivd.avi file to a DVD+RW disc, using ANY conversion/burning program the 2nd, and, any files I put on the disc after the first, the sound is out of sync with the video.
It's an annoyance, I'd much prefer that all the files be in sync, so as to make my enjoyment of the files complete. But, since the reason I write them to rewritables, is that I don't intend to keep the files, is not a fatal flaw.
Still, can anyone tell me why this is happening, and, is there a simple solution, other than only putting one such file on a RW disc, for this annoyance?
Thanks.

Again, a post with not process detail. It makes it very hard to point out where you might have gone wrong if you don't tell us how you got here.

If you are burning xvid/divx files to DVD as data for watching on a Divx player, and you have sync problems, then one of two things can be happening. Either the files were out of sync to begin with, or the player looses sync loading subsequent files. The act of burning the file cannot cause sync problems.

If you are converting to DVD then there could be a number of causes, but without knowing how you converted it is hard to tell you what to change. Things that generally cause problems include VBR MP3 audio, trying to join two files while converting, trying to join two files after converting.

More detail from your end might get you more specific answers.

Gunslinger;

The files I have processed are TV shows, alledgely orginally grabbed as HD, and, uploaded as Xvid.avi files.
The processes I have used to convert/burn are NeroVisionExpress, and, TMPGEncoder with it's accompying DVD authoring program.
I'm playing the files back on a Nexxtech portable DVD player.
Hope this provides enough additional information for you to provde more possible information on my problem.

Use g-spot or virtualdub to check the audio. I will lay odds that most of the troublesome clips have VBR mp3 audio. Most encoders have problems keeping this type of audio in sync. Some programs won't even open the audio. The solution is to open the file in virtualdub, and when greeted by an error message, say yes to have the header re-written. Then save the audio out to a seperate file as uncompressed wav (or CBR mp3, but that means compressing it again - not recommended). When you load the video into tmpgenc, replace the audio with the wav file you created. I don't know if nerovision allows you to use seperate audio sources, so you might not be able to use it for this type of problem file.

I had the same problem. The solution is farily simple, just a little time consuming.

My workaround:

For each episode that you want to put on the disc

1 - Use AVI2DVD to convert the XVID file.
2 - Use VOB2MPG to combine the separate VOB files into a single MPG file.
3 - Rename the MPG file to whatever you want.
4 - Open the MPG file in your default player and jump ahead near the end of the file to make sure that your audio is still in sync. If it is, then you're good to go, if not try something different than my workaround.

When you have all of your episodes converted simply import the files into NeroVision and make your DVD.

Hope this helps!

'slinger;
I've put three files, so far, into VirtaulDub, and, 2 have come up with that error message you've mentioned. But I'm not sure how I'm supposed to save the soundtracks seperately as .wav's and still have the video files processed. I think I remember how to load the seperate files in to TMPGEncoder, so that it will process them into file for the DVDAuthor, but tell me how to do that again as well, just to be sure.

To do the audio, go to Stream / Stream List, and you'll see the "Save as WAV" button.

VDub-Mp3-freeze handles VBR MP3 better than VDub. Would try that first IMO. Still possible to get occasional sync errors though but nowhere near as often. I usually open files with VBR in Goldwave, then save as CBR MP3:-easier to then for me to encode to AC3, 5.1 etc etc as 'new' audio source and add into authoring app.

[agent222]

I tried everyone's suggestion, except for the Goldwave program, and, found that the next simplest to the V-Dub solution is the one that seems to work. When I ran the files through V-dub "regular", and, saved the .wav file seperately, the results seemed to be worse than if I hadn't. But using VirtualDub MP3 Freeze, and just processing them through that, no saving a seperate .wav file, in 5 out 6 files I've used this method, the video and teh soundtrack seemed to be in "perfect" sync. An added bonus, it converted them all to the 4:3 screen ratio, from the "widescreen" HD ratio.

I use virtualdubmod without issue.

How on earth can such butchery be considered an "added bonus" ? Are you insane ?
