My equipment is as follow
VP50pro - Vp
TR-XS805 receiver
VPL VW200 - projector
BDP 1400 - bluray
A35 - HDDVD
eic......

Should I connect the HDMI's to the receiver (passthrough) then to the VP50pro then to the PJ?
Or there the other way around?
I tried to search the subject but couldn't find anything.

Any input would be appreciated,.

if you have three hdmi devices it really does not matter if you connect to the receiver first or the VP50. If you need a 4th connection then connect to the VP50 and then to the receiver.

Either way, I would have the receiver in passthrough mode as the scaling of the VP50 should be the best in your chain.

hope this helps

Thanks Cubesys for the quick response I really appreciated.
