I have a Sony 5200es A/V Receiver with three HDMI inputs.

Latest HD Direct tv satillite box with HDMI output

Blue Ray DVD with the HDMI outputs

My TV is a mitsu HD with no HDMI inputs

My question, Would it be possible or would I gain anything if I connected the Sat Box and DVD HDMI Connections into the A/V Receiver with out being able to connect a HDMI from the receiver to the TV??

Thanks for any help.
