Try increasing the dlna alive message interval to 1800. Also why not use our LG app instead?
Reinstalled 3.5.2 , increased DLNA alive message to 1800 and also updated the LG App and tried it - it was coming back with "No playable stream available" error after 10-15 mins before this.
So far i'm not seeing an issue now but i'm not sure which steps i took below fixed it :-
1.) Increased DLNA alive message to 1800
2.) Changed OSX Energy Preferences for the computer to "Never go to sleep". Before this it was set to sleep after 10 mins which corresponds to when i get a "Network Unstable" or "No playable stream available" error on DLNA and LG App respectively.
I believe the problem i was facing could be due to the OSX settings, what baffles me is i've never made changes to those settings. Will continue to monitor today and see what happens.
@Luke do you think we will ever get the feature to change subtitle colors on the LG App?
