FYI steve, you can make a playlist of videos on Youtube, and then someone only needs to click on the playlist and youtube will automatically redirect them from part 1 to part 2, and so on.
Another thing many people do is make part 2 a video response of part 1, part 3 a video response of part 3, etc.
I'm not sure if you've done these since i just downloaded the audio of the movies using
Convert Myspace Video and Youtube to Mp3! Only at VidtoMP3.com. My dial up is insanely slow when viewing youtube videos.
