Hi. I came across this site recently and I've enjoyed reading many of the threads, especially the technical stuff. I'm a retired electrical engineer who worked in the telecom industry for 40 years. I've been interested in high end audio since my teens. A lot of my stereo electronic gear (amps and preamps) is home made, mostly stuff from Audio Amateur magazine. I got interested in home theatre around 2000 and built a 5.1 system using some of my previous equipment and a new AVR and dvd player. Then I started collecting concert dvd's and blu-rays. So my experience with multichannel music is limited to my concert dvd's/br's. One thing that always bothered me with concert dvd's/bd's is the awkwardness of changing discs and moving through the program material on the disc. My dream scenario was/is to be able to create and play lists from my concert discs in multichannel sound and hd video. I tinkered with some approaches but was always limited by file playing capability of my old WD TV media player. So I was very excited to discover the Multichannel Media Players thread on this site. It seems to be the path to my dream scenario of listening/watching playlists of my concert disc material without breaking the bank. I do have some questions I'd like to ask, but I'm not sure where to post them. I'm thinking it would be best to post questions in a thread related to the question, right? For example, is there a good approach to extracting the multichannel audio from HDMI and converting it to an optical signal that can be handled by an AVR? My AVR is old and does not have HDMI inputs, but it does have an optical and coax input. Thanks!
