The ONLY good thing about the cable DVR's is that you can record 2 things at once - the Tivo's that run off of cable boxes can only record one show at a time.
Of course, using my theory above, at least I'd get to see the shows that I put in to record
We have 2 TiVo's anyway, so if there were 2 things on at once, we'd put one on the main TV & one in the bedroom.
