iirc the display framerate on the screen is not representative of the recorded. Recorded file takes precedence to displayed image.

Your file is missing any codec information/moov atom. I tried running it through https://github.com/ponchio/untrunc - using one of my HD files but no luck. Might be someway of getting the information out of it.

Theres also some suggestion here http://talk.maemo.org/showthread.php?t=84800
