I hate to advertise for big media, but I can't help it this time. I must tell my geek friends: The CBS Web site is streaming, for free, all of the original Star Trek, two seasons of The Twilight Zone, MacGyver, and a few other old shows. There are a couple ads during each show, but they're short (like 15 seconds). The videos play in a 640 x 480 Flash window - pretty much what you get on a DVD. It'd be nice to play them full screen, but I can't; maybe a full version of Flash would do it.
Boy, this is really gonna help me get work done during the day!
