This problem has been recurrent and seems to show bugs in red5. We're using red5 as the video server. We had a problem with the video file only containing part of what was recorder, but found it was only a bug in the current version. I then downgraded red5 to version 0.9 and all of a sudden the video portion of the playback wasn't working.
When this happened before, I was able to fix it by opening a port, but the same didn't work this time.
Has anyone had this problem? Any ideas of what may be wrong?

Thanks a lot!
