I just wanted to check the best way of wiring up my shiny new AV kit.

What I want is 5.1 sound from it all.
This is what i have...
A Panasonic PZ70 (2 hdmi ports, but have 3-1 hdmi adaptor)
A Toshiba EP30 HD DVD
A PS3
A Freeview box
A Sony DAV IS10 surround sound system
(also have 3 optical cables and a 2-1 adaptor)
This is my best guess...
Sony > hdmi > TV ...so I get DVDs / TV with 5.1 sound
Tosh & PS3 > hdmi 3:1 convertor > TV
Tosh/PS3 > optical from each into 2:1 adaptor > Sony...so I get 5.1 sound from them
Freeview > scart > TV
Does this look right to you?
