Why does quicktime stop showing video
Running version 7.6.2 of quicktime
When I play my video every so often the video stops moving or goes away (still have audio).
Files are .mp4 format.
Would be great to have quick time work.
Without a GUI, mplayer will show a "console" window, which will give you more details on the file being played, and will indicate if there is a problem with it (file damaged, keyframe missing, etc.)
I suppose you're on windows? You can install Quicktime Alternative.
Or even better, and not windows-specific: you can install VLC. Plays .mp4 out of the box!
