I happily use idvd to make DVDs. I am lucky my DVD player handles full screen dvd mpeg2 at up to 6M so I also can make great quality XSVCDs. I am currently trying to make some XVCDS from some of my old DVDs. Problem is unless I recreate the original .MOVs from DV I need to use the VOB. I am having problems converting the resulting idvd vobs to mpeg2s. idvd seems to use PCM audio. Great tools such as FFmpegX seem to fail to handle the PCM. I can extract the elementary streams using standard mac X tools, but every sound tool (mostly 0S 9 unfortunately) I then use to convert the pcm to ac3 or mp2 for remuxing, produce corrupted audio files.
I love my macs but I am slightly tempted to run virtualpc and use some PC tools. Please help stop me from going to the dark side.
Does anyone have success converting idvd vobs to mpeg2 (or .mov) cleanly??![]()

If you find your idvd project, right click it and choose "show package contents". Buried in one of the folders is the mpeg2 file. You don't have to burn the disc first; just add the video, and wait for it to finish encoding.

Thanks but if I still had the DVD project around I would also still have the original MPEGS on my disk also. My question is in regards to retrieving the mpeg from a iDVD vob if that was all I had - an IDVD DVD. I am trying to make some XVCDS from some older DVDs I made last year.
Any ideas on how I can get clean mpegs from an iDVD vob (with PCM)??? -
Same problem with DVDSP encoded with aiff or wav audio. The pcm extracted from the vob seems to the wrong sample or endian.

Well I gave up on a mac tool to extract a MPEG2 from a idvd (or DVDSP) vob. For future reference it can be done using Virtual PC for just one step.
1)rip the vob with OSex - I get both a program and elementary streams. throw out the PCM stream keep the MV2.
2)in the tools option of tmpgenc under virtual pc, do a simple demux of the program stream. Only extract the pcm, which is saved as a WAV file.
3)convert the WAV stream to a MP1layer2 file (I use mac cleaner 6).
4)mux MP2 and MV2 into a mpeg2 using mux tool of FFmpegX.
Results in perfect MPEG2s. I then use the resulting MPEG2 directly in my XSVCD or use FFmpegX to make normal VCDs or SVCDs from this mpeg2. Interesting it proves that idvd simple encodes at 5M for 1.5 hour dvds and 9.8M for 1 hour dvds. No intelligence used.
Possible advice: From now on when I burn an iDVD, I will archive the audio tracks around (in mp3 form prob) so I never need to go back to Virtual PC.
If anyone ever comes up with a better way please let me know. Thanks
