Is anyone else having trouble changing live channel? My TiVo seems to love Discovery+1 (213).
If I go into TV Guide, find another programme/channel such as Criminal Minds/110, and press OK, it switches to live TV, momentarily shows the banner for 213, then momentarily shows 110, then reverts to 213 again. It's the same if I press Play. The 60 minute buffer is trashed, so I guess it has done something to the tuner I am watching. I can change channels OK if I type the number directly, just not through the TV Guide.
I had this problem earlier this evening. I've ignored it and it's been recording programmes on diverse channels quite happily; I had 2 concurrent recordings going so it must have moved both tuners off 213. However, now the recordings have stopped and I experimented again, it's back to 213. Weird. I suspect I've never asked TiVo for this channel because it is not HD.
[Later] I've now restarted TiVo via the menu, and that seems to have cleared it.
