Finally got some time to address some of the playback issues. Next release should have the following improvements:
1. Better detection of whether a device will support direct streaming or if transcoding is needed.
2. If you button mash on the Movie view, you'll be able to move through the videos faster. This mainly affects Android TV devices that do not have a FF and REW button. If you have an Amazon Fire TV you can use FF and REW buttons to move faster through the list.
3. If you have a Plex Server and and Emby Server, the app should be able to correctly and more reliabley switch back and forth between the two servers.
I still need to test this out on the NVidia Shield... and I should be receiving an Android TV ADT2 from Google at some point.
Still need to run it through more tests before putting up a new build.
