A couple questions:

1) Which MPEG2 playback library are you using in MythTV (check
frontend settings - TV - playback) See if using libmpeg2 helps (or
deselecting it if it is already selected)
2) Does Mplayer itself play MPEG2 video normally?
3) Does uninstalling Mplayer and the codecs resolve the problem? If it
does, give Xine a whirl and see if you get the same problems.
