@tmm1 @eric @maddox I think I found a bug with source priority being pushed down from the server.
I noticed that my sources were not in the priority that I set (pic1). Pic 2 (my ipad but it is the same for my apple TV's) shows the sources are all in the wrong order.
Now here is where it gets crazy. I removed all of the sources from the server side setting and then re added them in the order I wanted. This worked sort of OK, the clients all updated. The HDHR sources were correct but the m3u sources were not in the correct order. I thought no big deal as it didn't matter with m3u. So I chalked it up to a glitch and went on my way. Then I went to the sources in settings and noticed that I had one source that was not in my preferred place. Nothing big but I moved it (not in client settings but in regular settings of the server (pic 3).
After I did this the clients went back to their wacky sort order (pic 2). It seems like the client is not honoring the client setting after all.
