Movie Maker upload problem

[Guest laura]

whenever i try to upload a video i recorded through my WinTV, it comes up

with this message: "C:\MyVideos\_BBC ONE_20070717_193021.mpg could not be

imported. An interface has too many methods to fire events from"

Any ideas why this would be? Because i done one the other night and it

worked, and all of a sudden this keeps comming up. Please help!!
