[mythtv] XVideo XvMC VLD broken

[Terry Barnaby]

Here is a little more feedback on this problem.
It appears that the Xv/XvMC/avcodec system has not recondigured itself
properly after a channel change.

I have put debug messages in the libviaXvMC library to see what is called.
You should see a sequence like:

XvMCLoadQMatrix:
XvMCBeginSurface:
XvMCPutSlice2:
XvMCPutSlice2:
....
XvMCPutSlice2:
XvMCFlushSurface:
XvMCSyncSurface:

My enclosed attachments show some part of the sequence before changing
the channel (working1) and the first bit after (bug1).
The Via XvMC system gets a XvMCLoadQMatrix(),XvMCBeginSurface()
sequence then a lot of XvMCFlushSurface(), XvMCSyncSurface() (Getting
rid of buffers ????) then a XvMCPutSlice2() that fails as it no
longer owns the decoder (No XvMCBeginSurface() after the last 
XvMCSyncSurface().
