A quick question from a Roku 2 owner in the UK, but I'm not sure if I should direct this at the Plex forums or here, but anyway..
I'm running Plex Media Server on WHS 2011 and I've installed the Plex client on the Roku. All my DVD's were originally stored in VIDEO_TS format on WHS, and this works fine in the Windows Plex client, everything plays back ok. On the Roku though, I'd always get errors that the video file couldn't be found, so I tried converting the VIDEO_TS movie to MKV using MakeMKV. All this has done is take the MPEG2 video files and put them in a container. It hasn't actually done anything to the movie data itself. Anyway, when stored as an MKV, the Roku will play the video file fine, but I've noticed that even with a basic MPEG2 video stream with DD audio, the PMS is transcoding all the output for the Roku, so putting extra load on the WHS. While the movie does play fine, I'd have thought the Roku would have played back this natively (without transcoding), but it doesn't. I'd checked the Roku, and playback was set to 'Automatic'. When I tried setting this to Direct Play w/fallback, I could (most of the time) get the Roku to play the movie without transcoding being required, but it's still a bit hit and miss (sometimes it will transcode, other times it won't)
So, what gives? Does Automatic play cut corners with playback. What is the best setting to use? Am I missing something else?
