Problems w/ Recording Streaming Flash Video RTMP on WM Recorder

[superfanny008]

I'm capturing several Flash Video RTMP streams (I'd rather not say from where), but it saves properly for some of them (and very quickly too). But then for several of the streams, WM Recorder will begin the download properly and still say it is recording but the file is actually not increasing in size or nearing completion. The speed at which the download is going also freezes at a set amount. I tried re-recording and sometimes it works, sometimes not. I can't figure out what the problem is. Any thoughts? Is FLV Recorder or some other program as fast as WM Recorder? (I used Replay Media Catcher for a while, but its no where as fast as WM Recorder)

Thanks in advance, sorry if I'm not being clear enough. Just ask for more details if need be.

FYI, I"m in ADA mode.
