I've been using Emby for at least 2 yrs and on the whole it's great. But for some time now, I've been noticing an increase in the number of times playback suddenly ends. I'm not positive but I think this may be more related to playing ISO files. Everything is perfectly fine and then all of a sudden the movie ends and it's back to the Roku menu. Yes I'm using the Emby app through Roku. It's a hassle to get back to where video crashed (due to buffer delay) and sometimes it will resume and other times not. But the crash frequency is definitely rising. Any suggestions (and thanks in advance)?
