I did test your version of liblavrec. And it works.
The video is recorded properly.

I still have problems recording the audio stream but that might be 
related to the built in soundcard. I was not able to record with arecord 
either. I need to dig there a to find out how to choose the proper input 
recording seems to work. But I don't get any sound.

Is the current version of driver and liblavrec supposed to output the 
videos to the screen with mplayer, and be able to record at the same time ?
