I've encountered these problems as well where sometimes the audio/ 
video gradually loose sync with each other, and also where the  
framerate is doubled.

A workaround for the video being too fast seems to be manually  
specifying the input and output framerate.

I don't know of a solution to the gradual loss of sync though.

For what it's worth, these seem to be problems with ffmpeg itself and,  
being based on ffmpeg, ffmpeg2theora inherits them.
