I have just purchased both a ReplayTV 5040 and a 5060. When either unit is plugged in, I get snow on the lower channels 3-6 and also in the mid 40s. This is only when the ReplayTV is plugged in - but turned off. The snow is when I am watching cable channels with the ReplayTV turned off. If I turn on the VCR and watch the cable channels, I do not get the snow. I replaced the VCR thinking that was the problem with a brand new one and still have the issue. If I am watching thru the VCR or thru the ReplayTV, I get no snow. This is an older TV (has coax input plus antenna). How can I shield the signals from the ReplayTV. I tried aluminum foil between the ReplayTV and the VCR - but this did not help the situation. I haven't tried putting aluminum foil between the TV and the ReplayTV.
