[mythtv-users] High Quality SDTV output

I'm getting ready to build a MythTV box and my big issue right now is
how to get high quality SDTV output from the machine. I do not
consider the s-video output port found on most video cards to be
anything close to high quality. I am not aware of a video card that
will output a true 480i signal, all of the ones I'm aware of force
the image through scalers which destroy the quality. I want to be
able to take interlaced video in, keep it interlaced while it's
encoded, and then output it as interlaced video. I am also aware of
the Hauppauge PVR-350, but this card seems to have a number of
compromises with regards to non-MPEG2 output. I do want to use the
MythTV box for AVIs, MP3s and console games (SNES, etc.). I am
vaguely aware of Cory Papenfuss's VGA to NTSC transcoder but my
soldering skills are pretty poor and I can't seem to find the
schematics anymore. I've also seen on this list that some newer
nVidia cards can do component output but I haven't seen anything that
confirms that they can do a 480i signal. Also, these cards seem to
have some issues with Xv video acceleration. With that said, I hope
some people on this list know of some cards or tricks that I am not
aware of, or areas where I am just plain wrong. Right now I am only
looking for s-video or component SDTV only.
Thank you,
