Hello,
For the last couple of days I've been doing everything I could think of
to solve this problem.. Although the solution seems a lot more close
now, I've not been able to solve the last part. I have spend hours
looking for a solution on the internet too, so this is a last resort...
I have also checked this list's history to make sure I wasn't asking the
same question someone else asked.
I will greatly appreciate all the help I can get, so I hope someone can
point me in the right direction.
All tips and hints are welcome!
- The problem:
The problem is that I'm getting these horizontal colums of lines over my
screen in full screen mode. When the window is small however, I am
getting a perfect image.
I have made two screenshots to illustrate the problem:
fullscreen, with distortions: http://www.techisg.org/~don/tvshot.jpg
small window, perfect: http://www.techisg.org/~don/tvshot2.jpg
- Background information:
At first the image was a complete disaster in fullscreen, because half
the screen wasn't shown. When I turned off 'P2C/C2P Concurrency' in my
BIOS, I got a whole screen but it left me with these distortions.
I've tried just about every BIOS setting combination availiable, but the
distortions won't go away. Further I tried about every xawtv commandline
option and every bttv module driver option.
If I start xawtv with the -noxv option I only get a little column of the
screen on the left in fullscreen, nothing more, the small size however
still works perfect.

It just starts working perfectly in a small window, when I go to full
screen the distortions appear as shown in the screenshot.
