Since re-installing XP SP2 (I had to replace the MB and a couple of HDDs) if I use the brightness control then the video turns to a purply colour with some green showing. If I leave the brightness alone then it seem to play OK.
I have installed the WMP codec pack which didn't rectify it. It mainly seems to happen with wmv file which play correctly when the brightness is turned up in VLC Media Player.
I have Quicktime isntalled and, of course, Vegras Pro 8.
The above effect was noticable before I installed QT and Pro.
Any ideas on what is happening and how to resolve it?
Cheers
