BTW. Remembered this old thread when installed PlayOn recorder a few days back.
http://playon.tv/features . It can be used to record streams on the Net. Had to buy it, since also use it to record from Amazon etc.
Needed it for recording a movie from YouTube, and it worked very well - but needed to try a few browsers and install the extension to both IE, FireFox and Chrome. Can't remember if it was Chrome that was able to record the best, but it's best to experiment.
However: haven't tried it with Live streams on Cam sites. Only with those embadded streams (the ones news/tv/YouTube use, and also most adult tubes). But I'm pretty sure it can capture recorded CAM shows (if the cam site offers them) and you may view them after your subscription has ended. I'll let you know if I've got time to test with any sites mentioned on this topic...
