I only get 2 HD channels where I live (others havent converted over yet) but they all have SD towers here and right now I have a replay hooked up to cable that gets the analog stations fine but I was thinking when voom gives me a PVR I want to cancel my replay but w/o all the stations that wont work for me but I have tried before. Is it just a matter of giving the channels on the guide or is it a UHF/VHF problem?
