A problem recording some Ustream.tv

[tacofish]

I've used 3 different kinds of rtmp catchers, which are WM Recorder 14, Replay Media Catcher, and Jaksta.

For some streams, they will disconnect from the url it finds after about 40 seconds.

I've noticed a pattern here. On WM Recorder 14 anyway, the url comes up as rtmp://live_xxxxxx with the xxxxxx representing a random number sequence. When I stop recording the stream and try to catch it again, the number changes.

Is this a playlist? Or protection? In either case, is there a software that can bypass this? By, say, being able to catch whatever is coming from an ip and a port.

I thought WM Recorder could do this, but it always cancels even though I'm 110% sure the ip and port are right.

Thanks if you can help me.
