I too would be loving That 70s Show on DVD! Well, one of the titles in the thread I just linked to is Profiler, which most of us know is coming to DVD soon via A&E Home Video (although without episode #4, dammit).
But Profiler coming from A&E is because of the affiliation with NBC. Since That 70s Show doesn't have that same affiliation, I'm not sure that there is good reason to connect these together.
I hope, I hope that most of the stuff on that list makes it to DVD pretty soon!
