It isn't only the DVD; according to YouTube, the VHS is also bad.

I was trying to stabilize this a while back...it took a while to get the stab AVIsynth script to work, and once I got it working, I realized that although it did a good job of getting rid of the "jitters", it still needed another pass from a different plugin (I don't have the name off the top of my head) to get rid of the picture weaving all over the place. I was trying to figure out how to work the settings for that plugin before I got distracted by some other project.

BTW, if you're seriously considering this, you might want to consider uncensoring some of the lyrics while you're at it.
