Well, did I open a box of worms....

I thought I had it down until Pandy wrote,

"Use RG59 for the video and digital audio. There is no such thing as 'digital coax'", in response to my question,

"
The Componant video-in uses an RCA type of connector, right? Does this require a higher end more exotic cable for the best picture."

I was asking about the output signal from the Sat. receiver or DVD. I understood about the signal from the dish to the receiver and the cables for that.

Now with all of your helpful input, I finally get it.

I buy specific component video cables to connect from my Sat receiver and DVD to the TV. Ya hooo!!!

Does anyone have any idea what Pandy was talking about?
