Bob, I prefer TiVo over UTV for one simple reason, recurring recordings. When you set a Season Pass for a program on TiVo, it records the program whenever it appears on that channel (and you can have it record only first-run programs and ignore the reruns, if you want). When you set a recurring recording on UTV, it simply records that time slot each week (or daily if that's how you set it). When the network moves the program to another night or has a longer episode, UTV just records the timeslot you've asked for.
There are a lot of other TiVo features that UTV doesn't have, but the way the Season Pass functions was difference enough for me to choose TiVo.
By the way, effective September 17, TiVo's monthly charge will drop to $4.95 a month, and there's no monthly charge at all if you subscribe to Total Choice Premier.
