--- Comment #2 from Erich Hoover erich.e.hoover@gmail.com --- It's been a while since I've done an update to this, and it's worth noting that we found out the real source of the problem. The actual issue here is that the COPP interface is not implemented and some websites require this interface even if they don't require HDCP. We've collected a lot more information about this issue at https://bugs.launchpad.net/pipelight/+bug/1235918 .
