OK so I went the udev route and now see /dev/pvr_500_1 and /dev/pvr_500_2
but when I go to use these from mythtvsetup all I see is /dev/video0 and
/dev/video1.  The Card type I'm working with is MPEG-2 encoder card
(PVR-x50, PVR-500) for both.  Once that card type is selected I can select
/dev/video0 or /dev/video1 for the video device, but I expected
/dev/pvr_500_1 and /dev/pvr_500_2.  Am I crazy to expect those symlink names
to be available?  What am I missing?

Thanks for the advice
