DVRs are the best thing to happen to TV since color.
My very favorite thing is that I no loger watch commercials. Ever. Someone recently complained about all the political ads and I was like, "Oh, yeah, I remember that." It is GREAT!
You don't have to remember to record House everytime it comes on. You just set it to record House, and it records the show every single time.

Or it'll record just new episodes, if you don't want re-runs.
I love getting an extra 15-20 minutes. Since it is already recording House, I can goof off on the DIS for 15 minutes, then just hit the rewind, wait 5 or 10 seconds and start from the beginning. By the time the show is over, I'm caught up (because I FFd the commercials.)
And it is wonderful if someone knocks on the door or you have to go potty. Just hit the pause.
Another great thing is that if you're flipping channels and start watching some great old movie, but have no idea what it is, you hit a button and it tells you the name of the movie, who starred, and what it is about.
The only problem I had was once in a while I'd hit the pause, go away and come back and un-pause. Then, as I'm watching, I'll accidentally hit a button and change the channel. If it wasn't recording, then when I flip back I'm in real time again, and missed part. The trick there is to either set the remote in a place nobody can touch it OR just hit record so that if you accidentally change the channnel you can go back and rewind.
If that last paragraph didn't make sense, it will after it happens to you.
Oh, and DH can watch stupid, boring sporting events (and I can record what I want to see and watch it later.) I suppose it was always POSSIBLE to watch one thing and record another...we just couldn't figure out how to use the flippin VCRs. This is EEZEE.
Just beware! Once you get a DVR, you won't go back...no matter how much you think, "Oh, how great could it be?" It changes the way you watch TV forever!
