Finally built the HTPC but need help with PowerStrip, Dscaler & ffdshow

Hi

I finally built my HTPC (which I think is the easy bit!), thanks to all who advised me.

Now I could really do with some software advice for...

PowerStrip - Dscaler
Basically Im not sure if these programs are only needed if using a projector. Im not quite sure what I would need to do with them

As for ffdshow - I messed about with this but it only seemed to make the DVD picture worse (no matter what I did!), Im using TheaterTek and I followed the beginners guide @ htpcnews.com.

Im using a Gigabute 6600GT, I have NVIDIA PureVideo installed and a Samsung LE26R41BD

I just have this feeling that Im sitting looking @ all this kit i bought and somehow Im not quite getting what I can from it

ANY AND ALL HELP WILL BE GREATLY APPRECIATED
