I did some TV-out testing today; the results are interesting (for the 
impatient: there is kind of a real tv output).

The results are on http://openchrome.wz.cz. There you can download xorg.conf 
and Xorg.0.log, see 15 photos with commentary and watch the Terry Barnaby's 
test video output.

I have never setup TV sections in xorg.conf, so I would much appreciate if 
anyone with experience could skim through it and tell me if there is some 
obvious wrong setting.

What I also noticed is that after X shutdown, there still was some flickering 
on TV, (the TV was black and random white clouds of dots travelling fast to 
bottom of the screen). Before *first* X start, there was no output on TV 
(perhaps the driver is missing some kind of a TV-out cleanup on shutdown 
of X?)

I did normal system startup (Gnome 2.14). There was some output on the screen, 
the positioning of elements was wrong and some parts of screen were 
distorted, but e.g. there was enough continuous undistorted place to 
reasonably work with terminal.

Btw. after the test I read the manual for the TV and it said that it accepts 
NTSC for "VIDEO IN", so I am not sure if "S-Video" is that case. I have 
tested only with PAL. (I will probably test with NTSC in the future)

More on the webpage with results.
