Ok, so basically this is an mplayer works myth doesn't scenario.

Do you know how many video streams are present in this file?  Is it
possible that MythTV is picking the wrong stream?  When I used Any-DVD
to rip Wall-E, the file I got had two video streams, one of which was
just black.  I appeared to have the same issue, as when I played it
back I got sound and thought I had no video, but in actuality it was
just playing back the "just black" video stream.

You can use ffmpeg -i to dump the info about the streams as described
at the bottom of http://mythtv.org/wiki/Bluray.
