Possibly alignment. I think a well aligned 70cm will still work, for now. I also think you should be able to see the channel on an HD PVR, even if your premium subs is not active. Have you tried to reset your PVR?
Pulled the power cable out to force a reset but still get the same "no signal found error". Guess I have to check my alignment / get to work on the big dish setup.
