GAH! Don't discard an AV. There are plenty of people who would take that off your hands, even sans CPU!

It can always be used to capture 320x240 video from a VCR. Whenever I dig mine out of storage, I'm going to use it to digitize the VHS movies my daughter still watches for viewing through our HTPC. Then I'll be able to ditch the last non-computer component connected to our TV.
