smplayer 0.6.9
os:debian squeeze
display card: nvidia geforce gt220
Some of the ,m4v files made by myself with Handbrake without autocrop, can not continue to play after either I press the pause button and then press play, or I minimize the window and then opened it again, until I move the wheel on my mouse or press right or left to +10/-10 seconds. But one of my m4v file of which the autocrop is enabled, can be played very well then, I am not sure if it related to the problem.
With mplayer itself, as well as the vlc player, the same files played very well. So I assume it's the problem of smplayer.
