Ok, i know it's 720p and 1080i, not 1080p, yea it sucks i bought it february
(good deal, was at my sisters so no sales tax, compared to were i live (yea
ask my wife the story of getting that in the back of our focus se sedan,
hehe but i meassured and i knew it would fit and it did, abet windows had to
be down a bit for a 4 hour drive, at nite in february) um no interest,
payments for 2 years, plus a 500 dollar gift guard, which i used to buy my
wife a really nice digital camera), anyways i tried puting mode "1280x720"
in my xf86config-4 file i belive under device, but it wouldn't work, so how
do i set a modeline for that? so i can get it to work, would really like the
higher res.

And do i still have to use deinterlacing? (which is best, kernel, bob,
liner,?)
