Thought I'd try Movie maker out. Yeah I know it is shit, I'm gonna get Vegas, but I just want to try it. I ran into this issue immidiately:

After having recorded some material from games I tried to get it into Movie Maker for editing, but all I get si a black screen in the preview window. I can hear the audio. I tried converting the files with VirtualDub and then importing, but get same result.

After reading around a bit on the Internet, it seems to have something to do with the updated Battlefield 3 Nvidia drivers? Or am I lacking some codec?

I'm running Windows 7 64-bit and the latest version of fraps. Any ideas? Basically I just want to quickly edit some clips and export to youtube, and from what I've understood that is all that movie maker is good for, but it is kinda hard when the video is just black

Grateful for any info
