Hi Darren. Welcome to HTF!
Here is a rule:
Only run video through the receiver if you have 2 OR MORE of the same connection types
Since you only list a DVD player, just run SVideo straight to the TV. Using the receiver as a switch is kind of silly if you only have 1 source. (There is nothing to switch to - think about it.)
TV:
Most people have a CATV or Satallite receiver or VCR that produces audio. In your case, you have the TV.
Yes, those are ANALOG connections. And you have to use them.
But dont get too upset that you dont have a digital connection. Once you get those speakers/receiver hooked up, I think you will find that network & cable television has rather poor audio quality compared to DVD or even VHS tape. It really does not justify needing a digital connection.
With that television (good one by the way

), you might consider getting a HD CATV box or Satallite receiver for HD programming. These usually all come with some type of digital connection for the audio.
Good luck.
