WM Recorder stops recording at 2gb

[noe]

I'm trying to record some flv/rmtp streams that are 2 to 3 hours long, but WM Recorder always stops at about 1:57 (1.99 gb). Then I get a message "flv file not ready." I can view the recorded part, but the recording is incomplete.

I've checked everything I can think of on my system ... max file size, etc. I couldn't find anything that would be doing this.

Specifics:
Windows 7 64 bit
6 GB RAM
600 GB left on my hard drive
NTFS file system
WM Recorder 14.10.1
