Determine whether this is an RF issue, or a DMA corruption issue:
1. Check the RF SNR of the digital cards using femon, anything odd going on when
the PVR250 is running? Does it fall out of lock or SNR dip dangerously low,
bursts of BER's?
2. Move the two cards as far apart as possible in the slots in the system and
repeat the test above, any better?
What happens?
