I still canīt figure out how to transfer VOB files representing recordings from a digital settop box (Sagem dbox II) to DVD format. The files usually contain the video stream and two MP3 or one AC3 and two MP3 streams.

Demuxing via ffmpegX does not work: While the video stream can be separated without problems, ffmpegX creates a multitude of supposed AC3 streams (up to six, even if there is no AC3 content inside the VOB) with a length of 0 bytes and deletes them afterwards.

Using "movie audio to mpxxx" works on the other hand, although I can only decode one audio stream no matter how many were included originally.

bbDemux does a better job by separating all streams correctly, but not one program I tried can combine them together and create a DVD structure (no matter how the files were extracted). ffmpegX works a few minutes creating an audio_ts and a video_ts folder, the first one being completely empty, the latter one containing a VOB and an IFO file, both with a file length of 0 bytes. DVD Studio Pro does not accept the mv2 files.

I can anyway convert the files to DIVX or other formats, although I mostly have to strip the audio file first and mux it back again after conversion. But as I go for quality rather than CD saving (a movie usually needs 2 CDs anyway), Iīd go much more for a DVD containing AC3 and another MP2 language stream. Seems to me thereīs something on the original VOBs that most programs donīt like (VLC has no problems with them, can stream them back, shows the correct number of audio streams). Is there any tool to analyse a VOB content so I donīt have to send the complete file and that hopefully contains enough hints to help major give ffmpegX the needed boost? Or did somebody already succeed in converting such files?
