I have the standard resolution TH-42PHD6BX. The Denon DVD-A11 and Netgem Freeview box feed a Yamaha DSP-Z9. So the DVD player, the receiver and the screen are all capable of converting signals. I would like to minimise the number of conversions / processing. What is the best way of achieving this, bearing in mind also that the Z9 only has one processor setting (and not one per input)? A further wrinke: the Yamaha claims that the Netgem is generating 576i signals, although I have the Netgem set to generate YPbPr Component (through a Scart -> component cable).
