Best way to set-up/cable the follwing . .

Hi All,

I've got the following kit:

Yamaha DSPAX2 av amp
5 speakers (no sub yet)

Toshiba 36ZP18Q TV
Toshiba SD220e multiregion (firmware 1.5) dvd
and Sky digital

Whats the best way to join them all up. I've also got a cd, md etc but these will just be connected using phono cables.

Should I use components or RGB scart, I guess digital from dvd to tv - but optical or coax?

I'd obviously like the best sound and pictures from both sky and dvd (its not a Sky + by the way)

All ideas and input gratefully recieved.

Also I'm in the US at the mo flying out tomorrow am so if you can reccomend quickly I can buy the cables cheaply over here!!

TIA

Dave
