Problems on the low-band (channels 2-6) are often the result of bad
connections, either poorly-crimped or loose connectors or broken
shields etc.
Trying to not get too technical, the higher frequencies can sometimes
"jump the gap" better than the lower ones. A terrible way to describe
it but sometimes useful.
Make sure you have the proper connectors for your cable, properly
crimped (ie: not with a pair of pliers) and the connectors are either
very finger-tight or just slightly wrench-tight.
The connectors on capture cards are sometimes hard to get at well
enough to be sure they are tight, sometimes easily cross-threaded.
Also you might try connecting a TV set to the exact same connector as
your card to make sure the problem is not actually in your cable
system or home wiring.
An easy check for this would be to swap the 2 cables connecting to the
PVR-500 and see if card1 now looks bad.
