It will be uncensored and unblurred. Including the famous "Chooclate sauce on the models" scene. It will also have a commentary by Matt and the creator.
The show was reaired on Spike after it's first airing with a commentary of sorts by Matt (and "The Smarmy Host"). That'll probably comprise the commentary. There was also a one hour 'interview' show with Matt after the finale as well; hopefully that'll be on the disk too.
