Thumbs way up!
1. Yes I use one.
2. Dish Network. (Hope they win the Court battle!)
3. I can record a whole season of my favorite shows, to automatically record when I can't be there to watch. Then I can start them when I want. Sometimes I can't get to my 7:00 show until 7:30, and I simply start watching it then, breezing through the commercials. I often have two channels taping at the same time.
4. There's only two channels to tape at one time, and you must watch one of them, or watch a DVD while both are recording. Sometimes I can't control which of the two shows comes on TV1, and which comes on TV2. In my house, TV1 is the living room, TV2 is the bedroom. If there are three shows you want to watch, you just miss one of them.
5. Several times a week, sometimes daily. There's shows I tape that my hubby doesn't like, I record them to watch on my lunch hour, when there's nothing on. I DO like my mindless tv and coffee at lunch to unwind.

Just a thought, if Dish loses the Court battle with TIVO, we will definitely be buying a TIVO with a lifetime subscription. I can't imagine going back to life without DVR.
