For me, Plex doeesn't work very well. I am only interested in the DLNA capabilities. I can't stream FLAC files (mp3 works fine) with Plex to my blu-ray player, which can play FLAC files. And I know it can do so over DLNA because it worked when I was using miniDLNA earlier. I have tried to get a custom profile to work without success, which Plex loads and associates with my player's requests, but doesn't honor the directplay settings.
I also have issues with viewing Photos using Plex. It doesn't give me the option to browse pictures "By Folder". I can only do "By Camera", or "By Year", etc. It takes too long to just load the set of thumbnails, and I have to browse through hundreds of them to see the ones I'm interested in.
Video works ok with Plex, in that I can at least play whatever I could earlier when I was using miniDLNA. On the plus side, updating Plex's index after adding new media without having to rescan the entire library or having to restart it, is wonderful.
I just tried DLNA from MB over my Samsung TV. It couldn't play the FLAC files (which it can't, anyway). However, the Blu-ray player was able to play the FLACs, which is a big plus for me. Only that, the blu-ray player listed the FLACs as mp3 (it lists them as FLAC when connected to Plex). So if MB was transcoding FLAC to mp3, they should have played on the Samsung TV too?
On the negative side with MB, now I don't get the option to browse my music "By Folder" :-(. That was an option with Plex.
