Hi, Someone once asked how to do this on a Mac, I've lost the original post, so I'm writing this to the list. You can do that with this utility: http://mug.imo.ee/bazar/tools/ASFrecorder-OSX.zip It's just the ASFrecorder utility that I compiled on OS X. I'll soon be working on a graphical front end to the program. Hoping this'll prove useful, -filipp
