I have tried replacing AV cables, etc - but I don't understand (and I really mean that!) how the TV or it's A/V cabling could cause the Hopper to split a 1 hour program into as many as 50 recorded "segments", on it's hard drive, and/or cause reboots? As I said, I certainly don't question the possibility - I just don't understand how the TV could affect the Hopper in this manner. But guys know a lot more about this stuff than I do.Well lets see you have replaced everything except 2 things I can see- the tv and you said you removed the power strip and plugged into the wall, have you plugged a power strip into a extension cord and tried a different circuit. Try disconnecting the HDMI cable and try using AV cables from the hopper to the tv and see what that does for testing purposes. If that does nothing I would say[Who you gonna call].
The one thing I haven't tried yet is trying to connect to a different wall outlet, or probably better yet, a different circuit altogether. Even though there are other devices besides the H3 plugged in, it could be that it is maybe more sensitive to spikes? Unfortunately, all my TV's are wall-mounted and the wiring for the H3 only goes to this one room. Yeah, I'm approaching the "who ya gonna call" thing here I'm afraid
