This weekend I've started playing about with
MediaBrowser 3. Looks like it will bring a lot to the party for me in that it integrates well with MediaPortal, provides the client/server model I miss from Plex and does media transcoding for handheld device playback.
However, this latest feature wasn't working well for me. I'd installed MediaBrowser Server in my TVServer Win 7 VM but when I tried to play back media from devices requiring transcoding (iPad, web browser) there was very poor performance, a lot of stuttering and general failure.
Even when I attempted to play back an audio track, it was skipping and pausing.
However, this reminded me of an issue I had when I had Logitech Media Server installed in the same VM. I'd get skipping on local tracks and a lot of buffering playing tunes from Spotify.
