After all this time, I finally got my own copy today (obviously as a Christmas gift). I must say that this is a great set, despite a few minor disappointments. For the most part, I pretty much skimmed through both discs, and mostly watched the stuff that was new to me. Those included the episode scenes for 1446 and 1576, I Say Banana, The first part of Weather Around the World, Big Hello 1-20, Snowflakes, Trash Outta Heaven, the original In/Out, the Behind the Scenes footage, the How to be a Grouch story, and the interview with Caroll Spinney. Eventually, I'll watch Episode 1316 with Sonia's commentary, when I get a chance. I especially loved the little character drawings that pop up on the menus. The booklet was especially fantastic (especially the character sketches and pullout).
But, all in all, Old School Volume 3 is a great DVD set, and I sure hope that Sesame Workshop and Warner Home Video bring out a 4th volume next year, or so!
