No crashes  here in ~13 tests  of about 5000 frames.   The only visual
bug or  bitstream bug i've noticed  is a "black MB"  problem. Some MBs
are totally black even in bright  zones, and some times i think the ME
algorithm is  just wrong because i  can see pieces of  characters in a
neighbour MB  (like a  arm which is  moving fast  and one arm's  MB is
coded as if it was "late" or swapped with a neigbour MB).  This occurs
always when there's medium motion or high motions scenes.
