Misplaced Picture

Hello
Kdetv works ok except that only 2/3 of the picture is visible.
I need to turn the tv scrrn in kdetv on the left and on the top in orfer to 
get the whole picture. However, no matter what I tried I have no success so 
far.

xawtv works 99%. The 1% is that the screen is just a bit on the right but the 
picture is 100% usable.

Is something that I can do about that problem?
 
Thank you in advance for your help
