[ale] Good TV tuner card?

Hi all,

As I prepare to build a MythTV rig, I find myself stuck trying to decide 
what kind of TV tuner card to use.

Of course, I'd like the pie in the sky solution: a card that works with 
Linux and Windows, can capture NTSC and ATSC (and QAM if possible), and 
all that jazz, so I'm not relegated to a single platform or signal, in 
case I decide to change things up one day.

About the best I can find is the Hauppauge HVR 1600:

It's getting a good amount of development (claims the history for the 
page), and has the old PVR-150 tuner for analog, as well as an ATSC 
tuner that Hauppauge/Conexant has provided firmware for.

In Windows, it pretty much just works, as good as Hauppauge's software 
has ever worked.

Does anyone else have suggestions for the holy grail of TV tuners?
