I'm running basic TimeWarner cable through their "tuning adapter" and am also using TW card.* After installing the "new" TiVo box it "hung" (not froze). Not froze because I could see the light moving in the TiVo background although the remote would not work.* Anyway, I took the tuning adapter out of the loop and it's been good for two days.* The TiVo tech (they are good) said that it sounded like the TiVo was trying to talk to the system bus (in the tuning adapter, I think) and that was hanging it up. * Anyone else had hang up problem after they installed a tuning adapter.
