As I wrote I created combined files using the guide from agressiv. Here are my findings: System: Plex Server: 1.22.0.4163 Plex Client: Nvidia Shield TV 8.14.1.23548 Fellowship of the Ring: Size is 151,818,076 KB Plays back in DV and TrueHD, audio in perfect sync The Two Towers Size is 147,255,233 KB...
