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
-- 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
