Error message when I load dvd into shrink

[photojoe]

I have windows xp pro operating system. Everytime I load the dvd into the dvd drive for my shrink program, I get an error message. it reads,
"E:\ This file does not have a program associated with it for performing this action. Create an association in the folder option in control panel."
I click ok and close the error message off, then continue. The program works but I want to get rid of the error message. I have a destination folder for the end product so I dont know what else it wants. I'm not great on understanding xp. I dont have any other problems other than that. Like I said the shrink program works fine, its that annoying error message I need to get rid of. Please if you have any ideas on this to try I would appreciate it. I have no clue as to what they want when they say to go the control panel options folder. When I go there i dont see what they expect me to do next. Please be specific as I dont understand the way this works.

Clean the disk is all I can think of.
