I've complained on these boards about the low volume of Netflix compared to Prime and YouTube. I thought maybe I was doing something wrong.

Turns out, Netflix meets spec and the others don't. The spec is called LKFS (see link). Netflix transmits at -18dB and the others at -13dB. So Netflix is 5dB quieter.
