With reference to VLC media player 1.3.0-git-20120114-0011 Rincewind and Win 7 x64
I have an intermittent problem where a video file is played and closed and will not play a second time although other files will. It may play 3 times then not play again or 1 time or 10 times. The player opens and then freezes without playing.
I think the problem is somehow related to WMP (32 bit) as I have occasionally enabled playback of VLC by closing the WMP process in Windows Task Manager and the problem is also more likely to occur if I play the file in VLC then WMP and try to play in VLC again.
