I agree about supporting folks who support Linux.

You should be aware that using those cards as analog tuners requires  
a lot of CPU because they are just straight frame grabbers, all the  
compression/encoding has to be done by your CPU. The PVR cards have  
on-board MPEG-2 encoders and thus take almost no CPU. You might well  
be disappointed with the analog performance of the HD 3K/5.5K cards.

Plus it's a "one or the other" proposition, you can't switch on the  
fly easily. Think seriously about a PVR for analog signals.
