No, thanks for telling me how to do that.  I piped it to a log and...

[muon][11:07:54 PM] grep -i xvmc /var/log/mythtv/mythfrontend.log
2006-11-20 22:51:31.508 VideoOutputXv: XvMCTex: Init failed

xine doesn't seem to work with xvmc either.

If I just run xine --video-driver xvmc 2121_20061120003001.mpg:

This is xine (X11 gui) - a free video player v0.99.4.
(c) 2000-2004 The xine Team.

and then it exits.  Strange that it does not complain about XvMC but
won't play either.  But if I run it without xvmc, with the -f flag to
get it scaled to fit, it plays jerkily like MythTV does.

So this is an XvMC problem, not a myth problem, but I still don't know
how to solve it.  I tried emerge libXvMC nvidia-drivers xine-lib to
make sure they are all linked to the same versions, but it doesn't
help.

see everything was just compiled today... I tried putting
libXvMCW.so.1 and libXvMC.so.1 in /etc/X11/XvMCConfig too.
