What sorts of bugs are you running into?
I can't play the majority of my media without getting the "Your connection to the server is not fast enough to stream this video. Check your Network." despite being on a wired connection. I can't switch subtitles or audio tracks without restarting playback. Half the time I can't resume playback of my media but have to restart. It takes up to a minute to forward/rewind (And sometimes doesn't work at all). Sometimes the library view doesn't show images for media until you reload the view. The GUI always have to reload entire views instead of single views on a page. Watch later repeatedly exits, and doesn't update properly. Sometimes playback fails to start (Rarely, but it does happen). And of course, it doesn't play a fraction of the codecs my library contains.
And that's just the things I can think of straight away. We switched to Infuse as soon as it came out, and won't be looking back as mentioned above, as it fixes all the playback issues I mentioned.
I love the Server side, and the Internet streaming part works wonderfully, short of the errors mentioned above. But the ATV client is a piece of junk.
I use this on a nearly daily basis without any issues. And to say it doesn't get any attention by the Plex team is completely wrong considering it is usually one of the first clients to get new features, like when they added News and DVR/Live TV.
I am glad it works for some at least. Looking at the Plex forums, I am definitely not the only one having a hard time, so I am not just ranting for fun and Internet giggles.
And sure, it gets new features, but they are always half-baked and bug riddled and non-functional for a LOT of people, and doesn't receive proper updates after - And if you don't believe me, check the forums. IMHO it is simply a scam to get more people to sign up for Plex Pass. Instead of fixing what they already put out, they want to include everything and the kitchen sink, on everything with a screen, and then forget about it. People can see their fridge can get Live TV by Plex, and buy Plex Pass, and then realize it doesn't work as advertised.
