Hi!

These are the files associated to the recording, both from the streams/1 and 
streams/hibernate folders:

All .avi and .flv files that include video have about 2 fps also when played in 
VLC. (Also the viewer integrated into OM has 2 fps.) If I understand this 
correctly, then already the video stream output by the recording applet outputs 
broken flv. That's why I never believed this would be an ffmpeg issue.
