I've already asked a few questions about my 'stock' HDVR2 (unmodified exc. for upgraded 80GB drive from Weaknees). I'm reasonably certain that its 2nd tuner really is dying, since the usual fix (using only composite video output) eventually didn't work. I have a 2nd HDVR2 that I'm subscribing (upgraded to Zippered 160GB drive, woohoo!) that'll go where the current one is (living room). What I'd like to do with the one I'm taking out of the living room is to put it in another room, eventually wiping/zippering (to 6.2a!)/networking it. It's set to run w/ one tuner now. But I noticed when I borrowed the 2nd cable last night (to download sat data into 2nd HDVR2) that it lost some channels and started giving me the "No Signal on Sat 2" msg. Here's the question- will an HDVR2 set up as a single tuner work with just one cable attached from the dish? The other room only have one line run to it now, and it'd be simpler not to have to run a 2nd line. Thanks!
