Well I don't know how but I think it whould be awsome if there was a converting app to convert ASF (A Windows Media Palyer type file) to a QuickTime movie or another Mac easy to read fourm.
...there really isn't a way, sorry Being the M$ is, well, M$, the /asf is a proprietary format so it's really hard to make a converter for it. You COULD get a prog like SnapzPro X and record the video directly off the screen, but itll take up mass amounts of space (but that can be fixed at least)
