I guess you did it within mythfrontend.
Can you try exiting mythfrontend and use the standalone player mythtv instead ?
call it like:
$ mythtv /path/to/file-h264.mkv
and see how it behaves ...
Also, I'm pretty sure mplayer doesn't apply any deinterlacing .. so try turning off deinterlacing in mythfrontend before running mythtv standalone ..
