I have to mention something about the Geforce4MX...it has an integrated =
tv-out chip...not anything familiar like the bt869 which is used =
extensively on a lot of the other nvidia boards....I bought one and I am =
disappointed with it due to the tv-out chip's lack of configurability. =
The tv-out tool "nvtv" won't work with it because the tv-out is =
integrated into the GPU chipset on the GF4MX. I used the closed source =
driver from nvidia with it,which works OK...BUT there was no option to =
tweak the scan modes or anything like that. Something to think about =
when it comes to the GF4MX. This does not apply to other GF4's though, =
just the MX. If someone knows better, please clue me in :)

Yeah, the gf4mx and an ati tv wonder should work.
