Okay, let's compare the TV version with the DVD version. In the TV version, the song when Lois is shaving Hal's back is "It's Your Thing." In the DVD version, it's "You Sexy Thing." The opening scene does have a couple of additional quotes and more quiet time. In the DVD version, as Malcolm is heading to the office, Caroline is reading a magazine (don't see that on the TV version). More quiet time during Mal/Stevie's scene; as Malcolm is telling us about saturday mornings, we find Lois in the background, heading to the washer; as Francis goes bye-bye for the day, Mal/Reese/Dewey are chatting about how lucky Francis is, and a scuffle is started about skiing in Alabama; additional quotes in dinner scene, bedroom scene, classroom scene; more quiet time outside.... so to make a long story short, same scenes, but more time.
