Thanks for your reply!

I have checked the settings for recording and it is set to 576 since I 
use PAL.
I also checked the version for the nVidia driver and it is 6629 (not 
6111 as I first thought).

I installed mythgallery today and I am getting perfect picture and 
colors.
I think the problem might be related to mythtv playback engine. The 
problem started when I upgraded to version 0.17. And all old recorded 
shows have the same problem when watched in the latest version so I do 
not think it is related to the recording part.
