I have an HR22 and a THR22 in my living room. The former is set to use IR remote and the latter use the RF remote.
But every once in a while, the THR22 starts responding to button presses on the DirecTV RC64 remote.
When this happens, I activate the TV's PIP to watch both DVRs at the same time. Sure enough, the THR22 is responding to both the IR and the RF signals. Then I have to go through the TiVo menus and tell it I'm using the RF remote in order to get it to stop responding to the IR remote.
Has anyone else seen this problem? It happens to me about once a month.
