Windows Explorer has encountered a problem and needs to close?

[MaPHacK]

Ok, so whenever I open the file on my desktop that has all my tv shows and movies in it I get that message. The Send Error Report or Don't Send kind. Then the file is closed by this problem. Then I try and open it again and the same message pop ups.

So I sent the Error Report and then clicked the More Information link and it took me to a webpage explaining the cause of the problem. It said that "This problem was caused by XviD" and I am assuming that is so because I just installed the ConvertXtoDVD software on my computer so I could burn avi files onto DVD.

And if I choose to ignore the message and continue leaving the file open i get this message "DrWatson's Postmortum DeBugger has encountered a problem and needs to close" and I don't even know what that is.

Does anyone know how to fix this?

Thanks.
