Okay this is then yet another issue. It is has neither to do with extermaly short recordings. Nor is it a playback error of VOD in red5. It is also not a recording error (this would be the case if you find ".ser" files in the same directory) It is an issue with the Screensharing Client from my point of view. It never has send the files to the server.
What you could do is: You could open a windows explorer (or similar :)) and watch the folder where the streaming data is stored. While recording is running there should be a file rec_12?_stream_??????????????_28_06_2012_13_11_20.flv.ser This .ser file should grow while you are recording. Can you verify that? Is the .ser file changing its size while recording at all? When you hit the stop recording button the .ser file should go away and the .flv should have roughly the same size like the .ser file previously.
