Keep in mind that a "real" (yet still not broadcast quality) RGB to NTSC
encoder is going to cost ~$500--and that is for an encoder *only* with
no rate conversion.  Not that I think a high quality encoder would really
help from what I can see of nVidia's output.  A transcoding TBC might help.
Unfortunately, mine has the component input option rather than RBG so I
can't try it. :(

I'd love to get an answer on this as well.  As it stands I'm about ready to
give up on the project on the theory that what I want cannot be done.  Because
my source is ATSC the PVR-350 is not supported for output, and from what I've
seen generic video card TV-Out technology has not advanced much since my last
exposure.  The problem is that generating a reasonable quality NTSC signal is
not trivial (TV Typewriter Cookbook to the contrary notwithstanding :).  You
can't easily tack on cheap TV-Out functionality to a VGA card and get quality

Ditto.  My other thought was to run IEEE1394 to a Sony DVMC or Miglia box
since they have high-quality "hardware" CODECs.  Unfortunately, that runs
into the dynamic transcoding problem again so it isn't supported and/or would
take too much CPU.
