Well, It was kind of a dry run with spare hardware not totally suitable to the task. Plus my interest diminished in pursuing QAM when it only netted me 1 or 2 channels in the clear that I couldn't get OTA ... (stupid adelphia *shakes fist* no LOST no MNF in HD for me via cable!)
I'm no expert but the fact that you don't have a consistent FE lock is most definitely an important part of the symptom/issue. It is possible that the HD-3000 is more sensitive to noise/lower strength signal than the QAM/ATSC tuner in your TV. In general with analog/NTSC cards I've found that to be true *shrug*. You could try running the cable directly from the wall to your HD-3000 (i.e. no splits/etc) temporarily as a test. If that improves your situation you may be a candidate for some sort of high quality RF amplifier or better grade coax or something... Although it sounds like you've sorta tried this. I have no idea if Dvico or other cards are more or less "sensitive" re: QAM/etc... My QAM tuner on my LG 30" widescreent CRT pulled in the exact same channels as the HD-3000. E.
