MST3K The Hellcats menu problems

[jwisdom]

Has any one else had problems with the menus on the MST3K episode "The Hellcats"? When making selections, Tom Servo drives by on a car as the new screen is brought up, but on my disk, the image breaks up and freezes for a while before bringing up the new screen. I had to eject it one time to restart, and some times nothing gets highlighted on the scene selection screen. I have a Toshiba SD-1600. I wanted to know if any one else had any problems, and whether replacing the disk is likely to solve the problem. (The store where I got it didn't have any others in stock.)
