  On my machine and mplayer0.90pre8 it depended on video - I usually try all possibile
 options for b_frames (0-4) and sometimes all work, sometimes some of them crash
  (mostly 1,3, but it is not the rule)

and with pre9 it sometimes doesn'tcrash, but encodes video to very short file and with very
bad quality - I don't know why... I think it is related together (because videos which crashed
mpleyaer 0.90pre8 now have problem with short and low quality output)
