I thought Replay A/V might be the ideal way to capture CBC's streaming Olympic coverage. It works great on active streams, but I can't find a way to capture streams not yet started. The streams use MMS, and I think are individually identified by a "reflector" parameter in the URL, but there's also an authentication key which I suspect becomes invalid at the end of each broadcast. So I can't pick up the URL for the stream at 12:00 pm to 3:00 am and have it work for the stream from 3:30 am to 6:00 am.

Any ideas on how I get around this, short of waiting up until 3:30 am?
