which of these HD TV tuners would be easier to get/write drivers for?

[Jim Stapleton]

I'm looking at setting up a multimedia center PC, and I'd like to base
it off of BSD, but the problem is that TV Tuners are hard to find with
drivers, and HD Tuners even worse.

Anyone know which of these would be easier to write drivers for? One
looks to be Phillips, one looks to be Connexant (examing the windows
driver files), dunno about the rest

could get a low profile bracket for this, I'd prefer that option)

(preferrably not, bad experiences with ATI)
