Hi NunyaBzness,
You shouldn't be having these kind of problems with the cable card and tuning adapter. If you have a 4 tuner card, we can balance it with 2 adapters and still get it working. There aren't many 4 tuner cards but I've worked with quite a few. Do you have the adapter connected at this time? Can you tell me what message you get when you tune to a switch digital channel?
