How can I extract infornation out of a TV tuner card ?

[foxclab01]

Hello to all.

I am creating a home theater with HVR3000. I would like to know 2 things :

1. The characteristics are :
CPU - Intel Celeron Dual Core E1200 1.6GHz S775
Memory - DDR2 2GHz / 667 / PC5400
Power - 450W
Video Card - Forsa GeForce 6600GT 512MB DDR2 PCIe w/DVI TV-Out
OS - XP pro sp2
Will I be ok for all the functions of HVR3000 or will I need something stronger?

2. I want to add an LCD screen in front of the htpc, that will display some information. Among that, I want to display the current channel of the receiver ( either by its code name or by its frequency is fine ). Is there a way to extract this info from HVR3000 ? ( either from the card itself or from the software ).

Thank you all in advance.
