If that's true, then that's a good reason to avoid the air2pc cards.  I 
know that pchdtv is funding some of the MythTV devs to improve various
areas, including some that aren't directly related to just the pcHDTV
cards.  One feature on their list to be done is the ability to save off 
separate streams from one channel, so for me that means that I could
record all 5 different PBS programs at once with one pcHDTV card.
I'd much rather have this functionality than saving 2% CPU usage and a 
little IO.  Also, when recording 4 shows at once now with 4 cards my
AMD 2600 it is 97% idle, so a couple extra % is not going to make any
difference in performance.

My guess is that the pcHDTV cards will stay as best supported cards for
an extremely long time.  They're purely a Linux company, for Linux.
They have paid developers to make things better including OSS projects.
And since the card is right at the same price as others, I'd much rather
support them then another non linux company.
