Playing YUY2 files
 

In short: How can you play them back properly?

I've tried to play them in WMP and VLC. VLC seemed to "work" but it had the color scale of a rainbow...
I want to do some testing with Lagarith using the YUY2 instead of RGB but currently I can't either play it back nor can I re-edit it after rendering since Vegas gives me an error.
