Hi All,

Nice improvements in the XvMC setup.  I just have a problem that I hope
you all can help me with.

I have two cards in my machine.  A PVR 250 and the cheap SAA7134 that
started me on Myth.  With XvMC enabled, I can watch V4L encoded live TV
and recordings.  However the PVR 250 output is not happening.  The
frontend stops with a "Unable to initialize Video" message and the
following output on the console ...

What am I missing here?  No amount of googling has resolved this.

I should mention that this happens for both recordings and for live TV.  There is no transcoding happening on any card.
The SAA7134 is recording in RTjpeg at 480x480 and the PVR is in native MPEG2 at 720x480.

Thanks!
