I've had to upgrade hardware, and migrate to a new backend, the old
PVR-150 card had to get replaced with an HVR-1800, I'm trying to just
use the analog cable input (but both it and the digital are being fed a
signal via cable).  When I try and watch LiveTV, I get a blan k screen
and then the menu, from the backend logs I see:

any ideas as to what's going on?   (BTW I did cat /dev/video1 > test.mpg
to ensure signal to the device and got a good file.)
