...then just rip the relevant titles and don't bother compressing them.

Various Linux media players will handle these just fine. I don't think that
that MythTV internal player does though. Although it's a pretty simple thing
to use an external player for mythvideo.

   mplayer has a dumpstream option that will extract the relevant stream files
and this will work on the vast majority of disks. Although there are still a
few "copy protected" disks that will give Linux tools fits. Disney and Sony
seem to be the biggest problems in terms of "broken" disks.
