Jean-Yves,

Mikes patch reduces the blocking probability significantly. Added to 
your change to cache the getframeswritten value, it probably more than 
enough  to make the dropped frames invisible. However the root cause of 
the stalls was the blocking of getframeswritten. I feel that continually 
calling getframeswritten to autoskip in progress recordings is a waste 
of time in most cases :-)
