I HATE live TV and commercials, but watching on DVD makes it that much more pleasant, especially when people with similar tastes recommend a show.
Oh yeah, I've also got Profit (which I adored when it was on originally)
and Wonderfalls. The nice thing about DVD's of shows which went off the
air before they finished the season is that you get to see where the creators were going. I have a friend who has taped all of Smallville for me, but there are some commercials in there.
Oooh Drew! You have the Prisoner! I watched that when I worked for a public TV station, and also have (had?) the full compendium book on the Prisoner somewhere. That was an excellent show. And Mrs. Peel, too. Love those catsuits!
