I updated not only the nvidia drivers (using envyng) but I updated
everything else that had an update.  118 packages updated.

The problem remains.

Interesting note.  I try and watch a program on myth and get just a
gray screen with digital noise blocks on it.  While that is going on,
I can watch that same program on mythweb with no problem.

I am still getting a variety of frontendlog errors like these:
2008-08-17 16:13:49.416 NVP: Couldn't find a matching decoder for:
/media/drive2/1111_20080817144700.mpg

and lots of these
2008-08-17 16:14:48.769 NVP: Prebuffer wait timed out 10 times.

The Xorg over active CPU went away but another time I got mythfrontend
at 100%CPU.

I just went down to the myth system.  Moved the menu to look at a
preview.  This is mythfrontend.log during that time:

Does anyone have a clue what to do here?  Is there something I can
post that would help?
