Absolutely!

It may be that my assumptions on the additions I put in for the PVR-500
in modprobe.conf could be the root of my problem.  I assumed that adding
the 81-1 and 81-2 lines were the ones I needed.

I don't see the problems you see with the PVR-350.  I get beautiful
output to the TV from the 350.  I do get a little static blips when
running the mplayer test but suspect that is the cheap on board video I
am using for the moment.  BTW: the mplayer command (mplayer -vo xv
/tmp/test_capture.mpg) worked just fine.  I think the -x11 option
cleaned up the little bit of static I saw.  But for me that is not that
important as I plan to use the PVR-350's output only once the box is
built and tested.

Hoping to have this new box tested up to the point of configuring mythtv
to point to the master backend.  Then sometime this weekend I need to
upgrade my master backend to 18.1.  That is going to be scary.  It has
worked so well for the last 7 or 8 months I just hate to mess with it. 
:)  That box is using a PVR-350 and a PVR-250.
