Hi guys

   Section 2.2 defines "API for Technical Properties", includes 
property setters 

RESULT setFrameSize(object framesize);
RESULT setCompression(DOMString compression);
RESULT setDuration(unsigned long duration);
RESULT setFormat(DOMString format);
RESULT setSamplingrate(unsigned long samplingrate);
RESULT setFramerate(float framerate);
RESULT setBitrate(float bitrate);
RESULT setNumTracks(unsigned short numtracks);

although these properties are all intrinsic to an encoded media file. 
It doesn't seem right to have setters for these.

Also, frameRate might be variable.  Are we supposed to report the 
long-term average, the frameRate 'at' the current playback position, 
or what, if it's not constant?
