Well, Malcolm's essentially correct in that if I knew anything, I would have mentioned it at TVShowsOnDVD.
I had originally bypassed this thread because yesterday was a hectic day for me (today still is too, but I have a minute).
But sure, I'm game to share my opinions:
Fresh Prince of Bel-Air...I think NBC owns the DVD rights to this, but would have to get Will Smith and Quincy Jones to sign off on it. I don't know if the latter is a problem or not. I think that this is much more likely to see the light of day under the new "NBC Universal" powerhouse.

Grounded For Life, That 70s Show...are all owned by Carsey-Werner, who hasn't put a single one of their shows onto DVD other than some Columbia House (subscription-only and expensive) releases of The Cosby Show. Personally I'd like to see those, but I think it's more likely we'll first see retail releases of The Cosby Show along with A Different World, Roseanne, Third Rock From The Sun, and Grace Under Fire. That is, whenever this studio gets around to doing DVDs at all.
Are You Afraid of the Dark?...I think Nickelodeon and distributer Paramount are concentrating on the newer cartoons, sorry.
Brimstone...seem to recall the name, but I never watched it and don't recall a thing about it.
Mad TV...my opinion is that the clearance rights to get this out on DVD would be too much, and that Fox would never do it. On the other hand, that was my exact opinion about In Living Color, and that's in-the-works! So what the hell do I know?

Alf...I think that the rights holders to this - whoever they may be - are seriously missing the boat on this item. I think it would sell nicely, if done right. If the rights holders read this and aren't a big studio themselves (or affiliated with one), I bet that Anchor Bay or Rhino would welcome a call from them! :wink:
Pirate Islands, Sightings...never heard of these, sorry.
I DO get an ego boost from being a "pundit" on these matters, but remember please that's it just one man's opinion, and that any actual *facts* I have are shared as I get them. Thanks,
