[linux-dvb] black borders in xawtv

[Johann Hanne <jonny@xiroi.de>]

Hi folks,

i'm still fiddling around with my linux based video recorder. After having 
found out how to get my nvidia-video-board to give me a nice PAL overscan 
signal (http://sf.net/projects/nv-tv-out), I decided to not use the 
composite out of the DVB board but the svhs out of the graphics board. DVD 
playback already works wonderfully, but I have problems with the DVB 
stuff.

I'm using xawtv just for telling the hardware to put an overlay from the 
DVB board on the X display - after quitting xawtv, the overlay still 
works. But the overlay region is not completely filled up with the TV 
picture, there are borders at the left, at the right and at the bottom of 
the overlay region. When taking a screenshot with xawtv, I get a 768x576 
picture (PAL size). When examinig it with a picture viewer, the left 
border is about 14 pixels, the right border is about 12 pixels and the 
bottom border is about 3 pixels. Where do these borders come from? Is it a 
DVB driver, v4l or xawtv problem? Is there a solution for getting around 
this problem?

Is there a way to put the overlay on the X display without an application 
like xawtv?

Thanks, Jonny <jonny@1409.org>
