Problem converting 4SVCDs to 1DVDR

[eldudereno]

I am attempting to convert an existing DVD rip on 4SVCDs back onto 1DVD. I merged the 4 mpeg2 files, demuxed them to audio and video, then recoded the audio to 48kHz. Then using Ifoedit I mastered the DVD with the 2 files. The Video is beautiful, seamless throughout the whole disc, but the audio is messed. At the point where the discs would normally be cut the audio starts wayyyy to early, like 30sec or so. So basically the whole first part is fine but then the audio goes weird and its downhill from there. I have also tried converting each disc seperatly and authoring them with DVDmaestro but the picture goes all to hell for some reason. Can anyone suggest any other methods?? I can convert each disc to vob files and they play/sync perfect but how to add 4 sets of vobs (basically 4 seperate small movies) without having to tear each one apart again and recode it. I have been at this for a few days and going batty. Any help would be much appreciated. Thx.

What program did you use to merge the mpg's. I find DV Tool does a good job.

I used TMpeg. It worked fine but as I said the audio goes to hell after the first disc. I have reripped the audio with DVD2AVI and Ac3'd it with Besweet but now I cant get IFOedit to accept the streams. Its weird. Ill keep playing with it. I did rip each of the audio streams seperatly in DVD2AVI as well and they did each have a delay

Update: Finally got Ifoedit to accept everything and authored the DVD fine. Tested playback and its perfect, so I burned a copy. Now when I playback in my standalone I get perfect picture BUT no audio. I put the DVD back in the PC and it plays fine audio and all. So I reencoded the audio again, this time in 5.1 and same thing. I cannot figure it out. I got sound fine when I ripped with Tmpeg but now that Im ripping with DVD2AVI I get nothing. But Ifoedit accepts the file fine and as I said It plays on the PC. Any suggestions??

Some DVD players do not support mpeg audio for DVD's,that could be your problem. I believe that mpeg audio support for DVD is optional in the DVD spec. Try putting one SVCD on a DVD-RW with wav/pcm sound and see if it plays the audio.

When I encoded the audio the first time I extracted with TMpeg, then encoded with Besweet to AC3. It worked, but out of sync after the first disc. Basically there is an audio delay between discs. So I re-extracted the audio with DVD2AVI and it added the delays, then I re-encoded with Besweet and the audio doesnt work, but as I said its perfect on the PC, no delays. And before I had extracted each file seperatly with DVD2AVI and the 2nd, 3rd and 4th files all had delays (-63ms, -73ms, -75ms respectively). So I am now re-ripping with Tmpeg and and going to use Besweet again but with these delay times added. Do you think the times are correct for each or do they just add on, so like only use the difference between the 2nd and 3rd (-10ms) for the 3rd file and the difference between the 3rd and 4th (-2ms) for the 4th?? Ill try it with the original times first. Any ideas why when audio ripped from Tmpeg works and DVD2AVI doesnt? Im confused as alot of ppl use DVD2AVI for making DVDs, but maybe not from SVCDS.
