You want an AV reciever m8.
I am using a Yamaha DSP-AX620, its pretty old now but does everything I need
My yammy had the following inputs:
360 (composite) + Optical
Media box (composite) + Digital Coax
Freeview (composite) + L/R Stereo
Dvd Player (composite) + Optical
Stereo L/R Audio only
and then the outputs were:
Composite to Telly
Composite to Projector
As long as you dont want HDMI/DVI or HD upscaling, you should be able to pick up a brand new receiver for less than £200 thatll give you what you need
I would sell mine but I cannot afford a new one atm
Something like this might do:
