<tt>I found when I use Bob, I need to use OpenGL Vsync to prevent
flicker. The checkbox is right under the deinterlace method.<br>

This is with a FX5200 to a 720p modeline.<br>

<pre wrap="">Thanks, I'll try it out with my Monster RF modulator.
I'm suspicious, though, that such a difference in
image quality might be due to the S-Video input to the
TV. I did manage to improve overall video quality
using "nvidia-settings". (Of course, I checked all
the "sync to v-blanks".)
In any event, my main problem remains: syncing myth's
output to the TV so I can use bob deinterlace. Has
anyone managed to do this with nVidia S-Video (SD)
output?

<pre wrap="">not sure how helpful my info is, but I've played
with a variety of pci
geforce cards with s-video out, with mostly the same

pretty sure that one of them was an mx440. the
s-video looked like
crap no matter what i did on any of them. one day
for fun i ran the
s-video into an rf-modulator that was run into the
tv, set to channel
4. the picture looked so much better that i just
left it that way,
even though its sort of hokey. dont know what the
rf modulator does
to the signal but it sure makes it look better.
