When playing any .flv file being captured from an RTMP stream, v0.8.0 Win32 stops playing the video either when it reaches the time point indicating the length of the file at the moment SMPlayer started playing the file, or at a point within 90 seconds prior to that time point.
When the mplayer.exe file from the v0.7.1 build is substituted for the mplayer.exe provided in v0.8.0, the problem disappears.
Can you post the location to a stream?
