"I have a Sony Handycam with a hard disk drive / Memory Stick Pro Duo. I can upload videos from either onto my computer and they will play. The problem I am having is that when I try to import them to Windows Movie Maker, I get this warning: 20090731112533.mpg could not be imported. An interface has too many methods to fire events from. How can i remedy this?"
Windows Movie Maker is notorious for only working well with DV-AVI camcorder files and WMV files. Any other file format that works was a stroke of good luck. Your best bet for editing the file would be to use some other software, but if that's not an option here are a few suggestions for getting past the error message and on to editing your movie.
