Uh, no, it shouldn't be.  ATSC is the encompassing standard, it
*includes* either QAM or 8VSB.  AFAIK, both PCHDTV boards support both
QAM[64/128/256] and 8VSB.  But, only 1 at a time.  You have to specify
the signal type to scan for when you do the scan.  Originally, I had
mine setup for OTA (8VSB).  Then, after my cable went digital only, I
connected it to my cable, and I rescanned as QAM-256.

According to the pcHDTV.com WWW site, they have a firmware download for
PC-2000 and PC-3000 cards which support

So, it seems that with the right firmware, your HD-3000 should do either
8VSB and QAM.
