I've been watching a lot of TV on DVD recently, probably because you can be more selective about which episodes of which series you want to see combined with the distinct lack of time-wasting commercials. Found this site called
TV Shows On DVD that tells you all about the current and scheduled releases of TV on DVD. If you're into that, it's definitely a site worth bookmarking.
Now the question is, when are they going to get around to putting
Voyagers! or
The Wizard on DVD?
