This is the thread on Shout! Factory's forums where much of the discussion on Mr. Belvedere takes place.
The first set won't be out until March 17, 2009. I'm not sure when they're manufacturing the discs, but if you have concerns/suggestions about it, this is the best forum to put it.
Right now, the main concern of the fans is whether the episodes are original network episodes (uncut) or syndicated prints (cut). Personally, I always prefer the uncut. Not that "uncut" meant anything restricted, but simply the fact that you get everything. Only a fan would really understand.
