is where you can find a very good article detailing many plans for many shows on DVD. No dates have been set, but I guess you can expect them in the next two years or so. Here is a list of the many many shows being considered (not all are dramas):

COMEDY
Good Times
Home Improvement (this is NOT official, it was just mentioned)
The Golden Girls (this is NOT official, it was just mentioned)

DRAMA
Dragnet
S.W.A.T.
Emergency!
Magnum, P.I.
The Rockford Files
Quantum Leap
Battlestar Galactica
Sliders
Charlie's Angels (June 2003)
Dawson's Creek (May 2003)

Nothing is really official, but expect most of what I listed (possibly excluding The Golden Girls and Home Improvement). Dawson and Charlie are only approximations by what is said in the article. Before responding, PLEASE read the article, it's very interesting! And I'm just the messenger, so don't blame me if these shows aren't released ;) lol
