I have a VIP222K upstairs with the TV1 output connected to the TV there. The TV2 signal is back fed into my home cable wiring so I can watch TV downstairs. Once or twice a week the 222 just starts ignoring the TV2 remote. I can take the remote upstairs into the same room as the 222 and it still doesn't receive the remote signal. I have to open the front panel and press the "system info" button, then the remote starts working again. I don't know what is causing it to happen but it is annoying to have to walk upstairs and press the button every few days. Any ideas? It is not a battery issue, I tried that.
