Hello. I recently purchased a Samsung HW-E450C soundboard and am tring to connect it to a Sony Bravia HX850 TV and an LG BP620C blu-ray player. Yes, I understand that I broke the cardinal in of trying to link different brands, but I have good reasons for doing so. I tried linking the three through HDMI cables, but then I couldn't get the blu-ray player to run. Is my only other option connecting the blu-ray player to the sound bar via digital optical cable, the blu-ray player to the TV via HDMI, and the sound bar to the TV via two-to-one stereo male RCA cable? I recently moved to Venezuela for work and want to make that I get all necessary cables to get everything to work. Thanks for your help.
