I've been looking around those tutroials you suggested, and, apparently, the "capture" feature of the WMP is no longer available on the free version; one now has to purchase the nifty version for that. It used to be included in the free version, but, as usual when software is "improved", all the good features are rid of, and a bunch of crap you never use gets added.

Ah, technology!

I guess I'll just wait to take caps using my college's computers. They have precious, precious Macs.

Thanks for your help, though!
