ITunes 9.0 and Music Videos

Here's a question:

I know Itunes 9 is supposed to be all DRM Free but the music videos aren't that way...obviously you could tell with older editions of itunes which videos were DRM Free or not.

So the dumb question is:
Is there anyway to tell which videos are DRM Free?... I can't spend two dollars everytime just to see if it is or not.

Thanks,
Robby
