I've got a Tivo HD that's been working great. Lately it's been hanging up but only after playing about 3 or 4 netflix streams. Basically, my son likes to watch a couple of episodes of Spiderman. Upon trying to watch a 3rd episode the stream never starts. If I back out and try another two the same thing happens, the stream doesn't start. If I back out and try to just play a recorded program (not netflix) then the whole Tivo hangs for about 5 minutes. After which it comes back to life normally (without having rebooted). I can even go back into the Netflix client and play one of the previously non-starting episodes. It seems like the Netflix client is somehow causing a problem that takes a while for the Tivo to eliminate. Anyone else had this problem?
