but, if you want to keep everyting hooked up simultaneously, I honestly would say to put the SVideo into the Recorder. Otherwise, you can't watch HD and record SD at the same time, since the Component will not work if sending an HD resolution to the recorder. You'd have to force everything into SD just to record. This can become frustrating after a while.
The newer Dish receivers output SD and HD simultaneously so that you need not ever toggle it if you hook things up right. My old model 6000 of course doesn't have that ability, and it is a PITA.
