Connect Yamaha RX-V773 Receiver to HDTV, Cable Box, Blue Ray and DVD Recorder

I have connected the above devices the following way but somehow Blueray player and DVD Recorder connection doesn't work:

Samsung LED TV - MUN55B6000VF
INPUT - HDMI 1 (DVI) AND RECEIVER OUTPUT - HDMI 1 ARC
DIGITAL AUDIO OUT (OPTICAL) TO RECEIVER INPUT OPTICAL (TV) AV4

Yamaha AV Receiver - RX-V773
OUTPUT - HDMI 1 ARC AND TV INPUT - HDMI 1 (DVI)
INPUT - HDMI 1 (BD/DVD) AND BLUERAY PLAYER HDMI OUTPUT
INPUT HDMI 2 AND CABLE/SATELLITE RECEIVER OUTPUT- HDMI
INPUT OPTICAL (TV) AV4 TO TV OUTPUT DIGITAL AUDIO (OPTICAL)

Samsung Blue Ray Home Theatre - HT-BD1255
OUTPUT HDMI AND RECEIVER INPUT- HDMI 1 (BD/DVD)

Bell TV Cable/Satellite Receiver 9241
OUTPUT HDMI AND RECEIVER INPUT- HDMI 2
SATELLITE IN COXIAL CABLES

Sony DVD Recorder - RDR GX-300
OUTPUT Component Cables to Receiver INPUT AV1
Digital OUT Optical to Receiver INPUT AV1 Optical

I have 5.1 Speakers but somehow INPUT for Subwover cable doesn't seems to work. Can someone advise what is the correct INPUT for Yamaha RX-V773 receiver?

Your help and assistance will be greatly appreciated.

Many Thanks.

Yes you are correct it is a Samsung home theater in a box.

Due to Samsung has limited number of HDMI and other inputs/outputs, I end up buying Yamaha RX-V773. By the way FR FL Center RR RL speakers working fine except Subower.

I will try to get an image of rear of Subower and post it tomorrow.

Thanks for your response.
