/usr/bin/xine -pfhq --no-splash -D -V xxmc dvd://<filename>.iso - 
works fine - this proves that XvMC works for other players.
Xorg.0.log - seems to be fine and is listed below.

I really believe its a subtle bug in the way mythfrontend works with 
the 6150 in fedora 8-64-bit as things seem to work fine in Fedora 7 
with the 6200.
