So I stumbled upon a weird “fix” for getting the DTS audio to transcode. Here is how it goes. I decided to create an optimized version for a file that has DTS audio, just to see if that would work on my TV. I chose “Optimize for TV” in the options. When that conversion was finished, I tried playing the file from my TV. The Plex server Dashboard showed it as playing, but it actually failed. But then, I tried playing another file with DTS audio, and magically, it was able to play the file. The Video was direct play, and the audio was transcoded to Dolby Digital. It was not able to do this before. After I deleted the optimized version that i created, it was able to play original file and several other files with DTS audio. So in summary, creating an optimized version for one single file with DTS audio, allowed me to be able to play all files which DTS audio. Even after removing the optimized file. It’s very strange, almost unexplainable, but I am thinking maybe transcoder was dormant, or something? I have no idea. I just know I can now transcode DTS audio. I did this test on another server as well and got the same result. Still can’t transcode video using the version of plex on my TV though (Plex for LG Google TV version 3.9.3b.309)
