Stumped on trying to buy a new receiver

[dommo92]

Alright so, right now I have a Pioneer PDP-435P that I got back in 2005. It might not show up on google because that's the Japanese name for it (Got it here in Japan) so the US name for it is the Pioneer Elite PRO-1120HD.

When I did get this TV it came with an onboard media receiver, a PDP-R05 to be exact. This receiver that I have is actually what I am looking to replace. Now, my problem is that I can't find a receiver to accompany my TV since my TV is connected to my onboard media receiver through two cables; one is a DVI connection for picture and the other connection sends control signals to and from the panel.

I've scoured the internet for possible receiver options but I can't find one that has both a DVI connection and a connection to send control signals to my TV.

Any suggestions on receivers I can purchase???

Oh and one last thing, if there aren't any receivers around, is it possible to connect my onboard media receiver to a brand new receiver?
