I recently reformatted my Mac Mini and installed El Capitan on it. While the Mac Mini seems to run a little faster overall, I now have issues streaming my shows to my Samsung Smart TV.
Some info:
1) I don't know that this is due to El Capitan but it seems to have started then.
2) The Mini is on wifi and the TV is wired.
3) This does not seem to happen always, but it happens more often than not. When it is happening, the shows are typically unwatchable. Buffering every 10 seconds or so for a few seconds.
4) Almost all of my content is 720p at 3-4Mbps according to Plex.
Any help getting this resolved is much appreciated! Thanks!
