In general, I have not had any network related problems with MC. The shortcomings are on the remotes' user experience and functionality.
Without digging up the posts that I have posted over the years, I can summarize network playback like this:
Audio: Works fine with JRemote, Gizmo, EOS when used as remote controls for DLNA playback. Usually flawless, but lately mobile playback has been working...or not. Seems random.
Photo: JRemote never worked for local mobile playback. Eos and Gizmo sort of worked, but lacking hugely on user experience.
Video: JRemote, EOS and Gizmo have been able to play back video on mobile for some time, but have showstopping shortcomings on functionality when used as remote for casting to chromecast/SmartTVs:
- Not possible to adjust bitrate
- Not possible to change subtitles (deal breaker for family)
- Not possible to change audio track (partly a deal breaker for family)
The full MC client running on network computers does all these things. My complaint list is related to using the Android remote only.
