[mythtv-users] Air2PC Rev. 0.20 cards

[Guy Paddock]

Hey guys!

Question: I understand that the Air2PC cards (the 1st generation ATSC)
really can't do QAM64 that well, and have no way of doing QAM256, despite
the fact that the BCM3510 chipset has the capability. As I understand it,
this results from insufficient memory on the card to properly demod without
buffer overflowing.

Is there any way to tell the chipset to pass through modulated, raw QAM256
data, to be demodulated in software? I'd probably be wicked slow, but I was
just curious anyway.
