The player started the piece ok but then 'paints' green on the screen and no more video.
The green screen of death.

I reinstalled my video drivers and that didn't help.
But when I lowered the resolution slightly from 800x600 to 782 (whatevs) the option just below that,
the content in vlc played. I used the Nvidia software with my card to change the screen rez.
What could cause this? I've never seen the problem before.
