How are you connecting your cable box to your pvr-250 (via coax/tuner, 
composite, or svideo)?

I've found that with a similar setup (motorola cable boxes feeding 
pvr-150s), mythtv would not properly tune the cards to channel 3 when using 
the tuner input. I had to use ivtvctl to manually tune them.
You might want to try that (assuming you're using the tuner input):
ivtvctl -d /dev/video0 -r 980 #(for channel 3)
