[mythtv-users] DVI vs. S-Video

I currently have an EVGA nVidia based e-GeForce 7100GS video card in my 
Myth box, and I'm using the S-Video out to push the TV-Out to my Samsung 
46" DLP HDTV.  I've been thinking about this for a few days, and I 
believe that I should be using the DVI connection from that card to my 
TV.  I have 2 HDMI inputs on my TV and 1 is being used to receive 
signals from my Comcast Motorola STB.

I'm a little unsure how to configure my xorg.conf file to do this.  
Also, I suppose that I'll have to get a DVI-to-HDMI cable.  Am I correct 
in this?  I'm adding my current xorg.conf file contents below, so if 
anyone has any ideas, I'm all ears.
