You need to go back and do some more research, as the HD-3000 doesn't MPEG encode anything. (ATSC is broadcast as MPEG, so no encoding is required by the recipient.) Most HD-3000 users also use a PVR-250 card for NTSC.
Check the list archives.
MPEG2 encoding. See the second line of paragraph 2 of the following link:
HD-3000 at pcHDTV <http://www.pchdtv.com/hd_3000.html>
The line I'm referencing is:
"The card receives NTSC and ATSC Signals and converts them to digital streams which are transported across the PCI bus."
I know that ATSC is already MPEG2, does this possibly mean that NTSC is converted to some digital format that is something other than MPEG2?
Yup! Digital != MPEG2. It's raw YUV data, not compressed.
I can attest that neither the HD-2000 nor the HD-3000 contains MPEG compression hardware. For NTSC, they are simply dumb frame grabber cards.

Ah ha...so it's basically an ATSC (MPEG2) tuner and a "dumb" (BTTV style) NTSC tuner?
It sure would be nice if it combined a MPEG2 encoder for the NTSC stuff along
with the ATSC tuner wouldn't it?
