Calibration of plasma connected to HTPC

I've read through multiple threads on the subject of calibration, but I still have some fundamental questions about how it works when you're driving the plasma with a HTPC. I know a few of you have such a setup (Esben, others), so maybe you can "clear" things up (bad pun, sorry).


My situation is that the HTPC is my ONLY source; I have no stand-alone DVD player.


Specifically: How do I calibrate to Avia using a software DVD player in a HTPC connected to the VGA inputs?

1. Do I make adjustments on the set itself?

2. Do I make adjustments in the software DVD player?

3. Do I make adjustments in the video card drivers? I'm using the Radeon 7500 drivers and WinXP.

4. Do I make adjustments using Powerstrip?


The bottom line question is, how do I know that these adjustments are meaningful, if the picture I'm seeing is produced by software that is itself adjustable?


Finally, are there any ISF-licensed calibrators that are familiar with HTPCs and can calibrate my display and HTPC software? I'm willing to pay someone to do it, if such a person exists.


Thanks,

Ken
