System sporadically stuttering usually after 1 hour of watching

Ok so I now have a question for you. Am I suppose to be on the beta upgrade cycle? I thought that beta software could have negative effects and thus should be avoided when having issues. I found this (see below), which says that I was in fact current for non-beta versions. CAN WE PLEASE STOP ATTITUDE, AND JUST FOCUS ON THE ISSUE. If you could kindly answer weather I should be on the beta cycle and explain to me how to get on the beta cycle I would be happy to oblige. And for now on please treat me like I know nothing to avoid any confusion. For the last 2 days I have been extremely busy at work (by 8:00 tommorrow i will have worked ( abut 30 hour in 2 days). I will try to get you my logs from both server and fire tv tommorrow.

Just as an update I watched my living room fire tv and it worked flawlessly (Watching the simpsons). I have since defaulted my master bedroom fire tv and reloaded only about 5 apps. I have noticed a possible issue with wifi (Plex says my internet connection isnt fast enough), even though the fire tv says it has great signal and it all tests show I have 150/150 and am using the 5g wifi. I plan on moving Master bedroom fire tv to Living and living to MB. I have also been experiencing some videos where the screen is frozen but the audio is playing, that happens quite a bit especially when starting plex and watching a first episode.
