Like I told a person who posted a similar question, It really depends on the type of streaming media
If they're Windows Media Player, or Real Player Videos - you can't go wrong with
WM Recorder.
If they're simply live flash (flv/swf) type videos - you might want to use
Replay Video Capture. Using the two of these programs, you can easily record just about ANYTHING on the net - including flash videos, live videos, webcams, live movies, etc.
Check out their free 2 minute demo here:
Replay Video CaptureThe only downside to the demo is - you have to re-start the program each time you want to record two more minutes :(
But over all, great program - I love it
Good luck!
