[mythtv-users] Mencoder magic for Internal player

Not a question to burn any brainpower over, since I have a working solution
anyway, but it might be nice to see if I can improve it.
Problem: I've got a fair number of Matroska rips from HD-DVD, transcoded via
x264 down to 720p from 1080p. Since I've got a 720p LCD HDTV, leaving it in
1080p is silly, to say nothing of a CPU-hog.
Now, I know that the MythVideo Internal player (version 0.20.2) doesn't really
like Matroska that much. It plays, but fast forwarding and rewinding is a bit
of a dead loss. So I transcode them into MPEG-2 files via mencoder - takes
more space, but I can deal with that, and I can fast forward, remember
position, all that stuff. Problem solved.
So now I thought I'd transcode to MPEG-4 (DX50) via mencoder to get smaller
file sizes, while not beating up too much on the frontend CPU. The files play
fine in mplayer, but when imported I sometimes get framedrops, and fast
forwarding/rewind tends to be a bit of a disaster. Picture gets corrupted
until the next keyframe, audio doesn't silence when FF goes past x3. Lots of
people have described these problems - so nothing new here.
But since recordings transcoded via Mythtranscode into MPEG-4 play/rewind/fast
forward just fine, there must be a set of parameters for mencoder/ffmpeg
which will produce Internal-friendly files. Does anyone have experience that
could bring to bear here?
I know I could also use Xine and Mplayer, but the integration of theme and
control from the Internal player is just too nice (and has significant WAF
All ideas happily entertained,
