Here's the framebuffer mode which worked for me which I had lying
around:
mode "1024x768-50"
# D: 49.181 MHz, H: 43.600 kHz, V: 50.000 Hz
geometry 1024 768 1024 8176 8
timings 20333 48 8 80 20 48 4
accel true
rgba 8/0,8/0,8/0,0/0
endmode
>From what I recall (these days, I just use freevo with dfbmga output
from mplayer), the output was very sensitive to the timings
values. For starters, they had to be a multiple of 4 IIRC, otherwise
things would go haywire in the way you're describing. There were other
bits of weirdness as well :(
I think I got something that worked by using an X mode & tweaking it
with xvidmode until I got something that worked (ie, filled the TV
frame with a solid image) then used an X -> fb mode style converter on
the web somewhere to get the frambuffer version.
