No, I meant to say lossy - meaning if use the audio analog channels on my 4K Blu-ray player, and connect to the audio inputs on my receiver, where do I encounter a lossy format? Sorry if I am not clear as I am not that schooled in codecs, etc. I tried to post a link to the manual for my Panasonic UB900, but since I am a newbie it won't let me post a link.
