I just purchased a Replay TV 5160. Was impressed with the component video out, optical audio out, and the size of the hard drive. However, ran into a problem. I have a hi-def satellite receiver (Sony SAT HD-100). I knew that the RTV would not record HD programming, and that was okay. The problem is that the RTV won't pass through any signals from the sat receiver unless I change the output mode of the sat receiver to the lowest level. Since I run my cable TV and OTA signals through the sat receiver, this impacts all programming. So if I want to watch ESPN off satellite, through the RTV (so that I can pause, etc...), the sat receiver needs to output at 480i (I believe that's the setting)which means I have to watch a lower quality picture. Further, I have the component video outs from the sat receiver going directly to an Audio Authority 1155 A/V switching box, so if I want to watch hi-def stations I switch outputs on the A/V box (no problem), but I have to also switch the output mode on the sat receiver back to variable (or 1080i). Not very convenient. Perhaps most problematic is that I will need to change the sat output mode to the lowest setting whenever I'm not home if I have anything targeted to record onto the RTV, otherwise it will not detect a signal!!!! Big problem. I have heard that there are sat receivers that can simultaneously output different modes (1080i and 480i for example). That would solve the problem. I spoke to RTV tech support today (very pleasant, and had no hold time ). He informed me that by the end of first quarter 2003, RTV will be pushing down a new software release that will allow my RTV5160 to pass-through HD signals, and to record them. Has anyone heard the same thing?? I was ready to return the RTV, but if this firmware upgrade will fix things for me, I am inclined to hold onto it.
