I got my copy today - the back of the dvd says:
"Relive the production of Sam & Max Season One, 2007 Style - by watching a DVD packed full of behind-the-scenes goodies made by game's original development team. (Yep, this is a video DVD that you watch on your TV.)"
On the disc:
Original Trailers & Cutscenes
Hours of Commentary Tracks
18 Time-Wasting Machinama Shorts
Blooper Reel
