Due to hardware issues (haven't bought my big HD set yet), and wanting
the additional channels (-2, -3 etc) and aspect ratio of HD, I'm looking
to take the output from my HD tuners and stream-convert to NTSC (that
is, *not* wait until the program ends). The goal of stream-converting
is of course to be able to use this for live tv when offline transcode
would be a pain, eg. Superbowl. :)
MythTV already supports LiveTV if that's all you're trying to do. Or
perhaps I misunderstood your question.
If you mean your frontend (or one of your frontends) can't handle
high-def playback, your best option for "live" transcoding from ATSC ->
NTSC is plugging the S-Video/Composite out of your cable box into a
PVR-x50. If you're using OTA instead of cable, you could get a STB ATSC
receiver (like

-- note that I don't recommend this one as I've never used it, but it's
the type of thing you would need).
Put another way, if your machine can't do playback (=decoding) of
high-def streams in real time, there's no possible way it could do
transcoding (=decoding + encoding) of high-def streams anywhere near
real time.
