Fishy indeed
Thanks for the replies!
I don't have a toshiba and i don't really use any other remotes, but i'll be on the lookout for related electronics. Thanks for the tip.
One possibility is that it's a wireless connectivity issue. The tv updates itself, so it's probably looking for signals all the time. Maybe if the wireless goes out, it'll wake up.
That might explain the itunes connection thing, although i haven't experienced that.
Just a guess.
