Looks pretty good.   The OSD looks as it should, as does the video while 
the OSD is present.  I can't say the same for any of the 0.17 builds 
without the patch.

Unfortunately, with XvMC enabled the system is still not stable.  If I 
skip forward several times in a row while playing a recording, the 
entire system hangs.  I have to power cycle the machine to get it back 
up.  I don't think that mythtv should be able to cause the entire system 
to hang, so perhaps something in XvMC is triggering a bug in the nvidia 
driver?   I'm currently running the 7174 drivers with my MX4000.  XvMC 
with 0.16 triggers no such hang.

On the other hand, the standard XV (no XvMC) playback looks good.  The 
only discernable difference is the increased CPU usage.   So I think 
I'll stick with this build and leave XvMC off for now.
