Before this app update, everything would play just fine on my phone - no messing around with options was ever needed. My server library consists of mp4's, avi's, mkvs with a mix of x264+AC3 or DTS or AAC audio, etc.) and haven't had any problems until now.
1) Since the app update (to 5.1.1.199), certain episodes of shows would play the video portion, but no audio. After looking around in Settings, I had to enable AC3 and DTS audio. Same with my Android tablet (which I updated recently, but it is not the same ver # as phone app). I understand not auto-enabling these options (as it is probably hard to auto-detect every device's capabilities) but it is not helpful to just play the video with no audio.
2) Forced to use Mobile layout instead of TV layout and it sucks. Example: I choose the TV Shows library on my server, and it shows me all of this "aired recently" and "recently added" nonsense but there is NOWHERE to just browse the list of TV shows that I've made available. Yes, I can search by typing in the title, but what if the user just wants to quickly scroll and tap through to what they want? Bring TV view back!! (please)
