One of the Christmas presents I begged for was the DVD of Dr. Horrible's Sing-Along Blog, and I received it with much glee. Over Christmas we watched it as a family a couple times, and it was great on the "big screen" (rather than the laptop). The other night I watched the DVD extras, and I must say: while there's the usual not-too-exciting filler like a "Making of..." mini-documentary, the piece "Commentary: The Musical" is really laugh-out-loud funny, full of the same somewhat irreverent humor from the show itself. I'm still chuckling to myself as I think about it. Recommended!
