I really like Replay A/V and can suggest it. It has many features no other stream recording software has. And it is very easy to use.

However WM Recorder is more powerful in recording Windows Media streams. It is very unique and can record media streams that no other software can't. If you record many streams, you will notice that sooner or later.

I have to repeat that I wish the WM Recorder advanatages were integrated into the Replay A/V.
