FLV Video RTMP stream 'freezes'

[superfanny008]

I'm capturing several Flash Video 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? 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.
