It is all basicly the same. You must have a high speed cable connection for best quality.
You get a Router you route to to setop box. then you use the Yellow white Red A/V cables and hook this up to a DVD RECODER via the input,, then you hook up your dvd recorder with second set of Yellow/white/red cables to you tv via Video 1 input or video 2 input.
Thats basicly it. you can thus record to dvd it's very easy.
