I have used a DVR for years. I record the shows I want to watch, watch them at my convenience, then I can just fast-forward through the commercials. I can watch a one hour show in about 45 minutes or less. I even do this for NFL footballs games, I just start watching the game about an hour and a half after it starts. I can watch a normal NFL game in about an hour or so.
I went to a relatives house last thanksgiving. We watched the NFL game live. It was agony. Three plays, 10 commercials, three plays, 10 commercials, three plays 10 commercials, I don't know how people stomach it.
I don't think I could even watch TV were it not for the DVR.
