    How can I convert a .vob file to a format playable by my new BluRay player?

    I tried converting it using AVIDemux, but I get massive audio sync issues. I even tried doing a stream copy into a MKV container and had no luck in doing so. I had the same audio sync problem.

    I did some reading and found out that MPEG-2 streams can be variable frame rate? If so, how can I correct this so that I can successfully stream copy it into a MKV container?

    The player supports MPEG-2 and MPEG-4 streams with AAC or AC3 audio using MKV, MP4, and AVI containers. I want it to be 100% of the original .vob because disk space isn't an issue.

    That's because taking only one VOB is almost a guarantee you will have sync issues....it has nothing to do with the tools you are using. Extract to one mpeg file with something like Vob2Mpeg and go from there.

    I ripped it using RipIt4Me and DVD Decrypter. Then I used DVD Shrink to remove the extra audio tracks and subtitles. I also turned off the file splitting feature in DVD Shrink so I ended up with a 4gb VOB file. The VOB file itself plays perfectly with no sync issues. So your saying to use Vob2Mpeg and then import the MPEG into AVIDemux?

  4. MPEG-2 by its very nature is already a very lossy format.
    VOB is just a container of streams, in this case: an MPEG-2 encoded video file and an AC3 (or PCM uncompressed) audio file.
    The only 'other' format with high quality that I can think of is h.264, but be aware that you can't obtain a quality higher than what your MPEG-2 has.

    If it is a new DVD....you better consider using tools that are not 3 to 5 years out of date....and a 4GB VOB file would always be bad news in my book. A VOB file exists for DVD proposes only and in the proper DVD structure a VOB file is limited to 1GB.
    Just start from scratch with an up-to-date ripper like DVDFabDecrypter....then use DVDShrink to remove the un-necessary stuff....output it to a proper DVD structure....then use Vob2Mpeg on that folder.

    Correct. I understand that. Then is there a way to do a stream copy to a MKV or MP4 container? The BluRay player I am using will play MKV and MP4 with MPEG-2 streams, but it won't play a VOB.

  7. The Blu-Ray player plays DVDs, doesn't it? So why do anything at all to the DVD?

    If for some reason you want a smaller size to fit on a DVD5, then reauthor your original DVD to make a smaller DVD. Use DVD Shrink to cut out the stuff you don't want and shrink the size. Or use DVD-Rebuilder to shrink it down. Or demux your big VOB file and add the audio and video to Muxman to reauthor it.
    I also turned off the file splitting feature in DVD Shrink so I ended up with a 4gb VOB file.
    A dumb idea if you wanted to get a playable DVD out of it.

    If you must have a single file, use MakeMKV to simply shift the video and audio content to an mkv container with no re-encoding, and therefore no quality change.
