Hi Carl,

I can reproduce this issue with VLC 1.1.8 on MacOSX and MPlayerX 1.0.2 for MacOSX (http://mplayerx.org/). I am pretty sure that this issue can be reproduced on Windows and Linux.
When you play back the sample file in VLC 1.1.8 or MPlayerX 1.0.2 on MacOSX 10.6.7, you will notice that the playback is extremely jerky (I can provide a 100MB file if needed instead of the 10MB). Also to fix this issue, the developers of VLC and MPlayerX should read the pulldown flags - apparently they currently ignore them.
