capturing live video feed to file
===

The SPEED network routinely plays F1 races and practice round etc. at o'dark:30 in the morning.  I'd like to capture the live feeds to my hard drive.  I THINK the feeds are some Adobe format, but Firefox seems very happy to present me with anything but the actual URL of the stream, without which information I can neither get to the stream nor have a hope of decoding it.

So, how does one avoid having to watch the race in the wee hours of the morning and instead spool it to my harddrive.  How do I determine the real URL of the feed?

If possible I'd like a gstreamer answer or perhaps ffmpeg, but any old answer will do either for Linux or Windows.  Preferred output would be something like MP$ or H264 and MP33 or AAC all enclosed in a Matroska container.

And, no, I can't see any DRM issue here.  The feed is broadcast unencrypted and if I were using a VCR I could just capture it.

Thanks.
