  1. let me try to make clear what i want to do
    i want to demux a vob completely and be able to reconstruct it without the original present
    i want this to allow me to extract the video and audio separately and compress them individually
    i then want to (later) re-convert the video and audio files back to mpeg2 and reconstruct the vob files to make the original dvd
    what i hope to accomplish is a way to store a potential 4.65 gb dvd in something like 2.5 gb
    my current thoughts are to compress the video using either lossless or high quality settings for xvid or divx or something to that effect

    the tool that ive used that comes closest to what i want is dvd-rebuilder but AFAICT, it still needs the original vobs present to rebuild the new ones

    please, any thoughts, comments, or suggestions are welcome

    Well, MPEG-2 is already very compressive, so it means that you're going to need use a codec that is more compressive in order to make the filesize smaller. This makes DivX, XviD, WMV and any other MPEG-4 codecs something like what you need for the video, and I would assume you'd look at AAC, MP3, OGG or WMA for the audio. It must be said though that the conversion to these and then a later conversion back to DVD-compliant MPEG-2 and AC3 or MP2 is probably (IMHO most likely) going to result in some quality loss for both audio and video. You're certainly not going to be able to restore the streams back to what you had to begin with.
    If in doubt, Google it.

    You cannot do what you want to do without (usually) considerable quality loss and more hard work that it is worth. As you are only backing up the DVDs that you own, there is no need to rebuild the DVDs when storage becomes cheaper. Simply re-rip from your originals.

    The best you can hope to acomplish is to reproduce a reasonable facsimile of the original video. It will take hours and several steps to encode and also to re-encode them back, with losses on each conversion.

    Why bother? Disks are cheap, keep the video as-is.
