Greenish/Redish Screen

[totty]

Hi everyone, Is anyone else having a problem with a Greenish-Redish screen while trying to play certain movies?
I am having this problem with some movie downloads while others are just fine.
I use VLC player and K-Lite codec pack(with Windows Classic).
It does not disappear with either of these players.
The colours over the movies makes them unwatchable in this state.
I am a regular downloader/uploader on the Torrent sites.
Thanks in advance for your help with this.
(Sorry if this type of Q has already been answered,plese link me to it if so.)

Since the color balance on some of the movies is good, chances are it is not a monitor or graphics card problem. It will have to do more with the codecs. K lite is the worst codec pack I 've ever seen. Most of my friends who tried it have had various problems like upside down picture, distorted pixels, bad colors in many videos.

VLC had it's own codecs and does not need codecs from K lite. So, try uninstalling K Lite as a first step and report back.

I am using VLC's own codecs, and everything plays like I am in a movie theater.

Thanks for your help kurkosdr.
I went into VLC video settings and unchecked the
'Accelerated video output' box and also the
'Use Hardware YUV->RGB conversions' box.
This has worked a treat and they are all playing great.

The always helpful safe mode! Glad it worked for you. What's the model of your graphics card?

I had a similar problem with the "Hardware YUV->RGB conversions" with a laptop with an ATI mobility X1600 video card. It converted to RGB 16-235 instead of the proper RG B0-255. As a result, the color range was compressed, the colors where not as vivid, and the black was in fact grey. To be precise 6% grey! Both with new and old drivers. Disabling the hardware YUY->RGB conversions solved it for me too.

Anyway try upgrading your drivers, it may work for you, and you might be able to enable accelaration again (altough the hardware YUY->RGB conversions are not as useful, accelaration is very usefull as it takes off cpu load). I never had a problem with the video accelaration on any Nvidia or ATI card with vlc, so if it's the hardware accelaration causing it, it will be kind of weird. Leave the hardware conversions off and enable the accelaration, and see if you have the problem again.
