GKnot/Divx5.2 causing too small avi's & slightly green?

With a movie length 1:34:49, and resolution 480*272, your problem is most likely that you have reached the maximum possible quality. Try using a resolution of 640*X.

Thank you kindly 

I'll try to set the resolution to 640 x something, thanx. I guess the green has got something to do with the small resolution also. Thomas
