[mythtv] QAM Issues with Air2PC

I just talked with John at BBTI (Makers of the Air2PC), and after some
discussion it seems that the NXT2002 based Air2PC is not QAM capable like it
had appeared before.. The Demodulator Nxt2002 is QAM capable, but there is
something else in the Tuner Module that doesn't allow it to work 100% properly
for QAM modes on some frequencies.. This most likely is some low level RF
issue, since it works perfectly fine for me on some frequencues, but on others
I just can't get a clean signal to save my life..

That being said when Air2PCs start shipping again they will be using a new
tuner/demodulator than the nxt2002.. Part of the design criteria for this new
board is that it function properly in QAM mode, so this new revision of the
board will take care of the current QAM issues and uncorrectable errors..
