I used your settings late last night, and I didn't notice an appeciable 
difference. I did notice a lot of 'smearing' for lack of a better term, 
in that when there was quick motion, you could see alternating 
horizontal lines that were out of sync in certain places on the screen, 
most noticable when there was  large difference between light and dark 
areas of the screen. I used your first posted settings (and I did notice 
that some of the options you described were not in the same sections as 
my XF86config file for some reason)

I should mention that I can't use XvMC since I get tons of those 
'pre-buffering pause' messages and lots of a/v hiccups with it, that go 
away when I don't use XvMC. I have tried the tweaks that have been 
posted to various messages but nothing made them go away. I have a P3 
1Ghz, dual PVR250's and the aforementioned MX440. With XvMC the CPU 
usage was minimal, now it's a constant 30-40%, but at least watching TV 
is smooth.

I need to go through this thread more thoroughly to see if I missed 
anything important.

Thanks
