Cory, just curious, what TV encoder chip does your Nvidia card use? My
old LeadTek GF4MX-420 card used an NV17 TV encoder and the output was
beautiful. That card has since died and I'm now using the onboard
GF4MX-440 from my Chaintech 7NIF-2 nForce2 boards, which uses an NV18
TV encoder, and, to quote you, it simply "blows chunks". You're about
the only other person I've ever heard speak of Nvidia TV-out that way,
so I was just wondering if you also had the newer chip.
I thought I'd be clever and get the VIVO one (this was 3 years
ago). It uses the SAA7108, which from the datasheet is limited to 288
lines IIRC. I've actually talked with an NVIDIA engineering guy who
explained how some of the newer ones work. They sound *much* better...
and go to a more hard-coded tvout when using an appropriate size (e.g.
720x480)
