@Maddox, I think what it is is actually a long standing issue. While you can disable Up Next it doesn’t truly disable as any new passes need to have the recordings uncheck Up Next as well. It’d be really nice just to be able to enable or disable the group in one place. My vote would be for in the client.
Also, I don’t want to gloss over the apparent loss of the ability to sort recordings by Recently Recorded, Alphabetic and Release Date. Alphabetic is very useful to us.
Yes, there's no setting to remove Up Next. It's a main part of the library. The setting you see is for the navigation. For promoting it to the main navigation, like I mentioned earlier. It's working as intended.
Browsing movies alphabetically can be done via the movie library now. Choose All Movies to get a single list of every movie in your library with different sorts. It defaults to Alpha. Add the Movies library section to the nav to get to this faster than going through Library.

@Maddox, ok, so I found where you can still get to sorting Movies and TV Shows alphabetically (and other ways) but I suggest to you that it’s not as intuitive or as easy as it used to be in the old interface. I like where you’re headed but, right now, I feel like your complicating the interface by forcing extra clicks and navigation to what used to be some really simple swipes.
As for Up Next, I read the forum daily (that’s probably too much to be sure) but from read it seems like Up Next is one of the more controversial features with many of the users either liking it or not. For the benefit of those who don’t like it we sure would appreciate a single point to turn it off so as not to be distracted by it. Just food for thought.

Thanks! Yeah, the idea before, when we had only a single point of entry, was that we could both show the most recently added movies, but let the More button be the "library" to let you sort them.
With Movies getting their own library view, I didn't want to confuse things, so I made the more button of Recently Added Movies (formerly New Movies, I changed it 
) ONLY be recently added movies, so that things were clear.
I fully understand your opinion and I'm going to be iterating on a lot of this stuff, The biggest issue really is that the library views are GREAT for people with big libraries, and TERRIBLE for people with small libraries. So striking a chord is going to be tough.
Keep a look out. I might just put the sort bar back on the more button for Recently Added Movies.
As a reply to your Up Next comments. Yes, those are comments from a very specific group of people here on the Community. There's tons of people that fully utilize and get value from Up Next that don't post on Community.
And as you mentioned here:
I feel like your complicating the interface by forcing extra clicks and navigation to what used to be some really simple swipes.
There's plenty of people that didn't like the old way either. 
It's our job to just hit a balance and ship the right stuff. And yah, a lot of this is going to be our opinion 
New build out
There's a known crasher in the last build. New build rolling out now.
Fixed build is available.
When you tap the “More” button in Recordings on iPad you don’t actually get any “more” — you just get a sheet which repeats the existing info already being displayed. You have to tap “More” again to actually get more options, such as the one I wanted (“Explore Show”). There’s also plenty of space on that screen to just have a direct link to the show…
It’s confusing that the word “Watch” is being used to indicate the action of marking something as watched when swiping to the right on an episode as well as to actually watch it! Also the word is only showing up on iPhone’s Recordings screen; iPad just includes the “eye” icon in Recordings. Perhaps “Mark Watched” would make sense as it’s used elsewhere in the UI, and the eye icon replaced by some derivative of the circle progress indicator much like Mail uses.
Had a weird issue this morning. Baseball game on MLB Network on my iPad. From the guide I pressed to record. The dialog went away, but no recording started. Looking in the DVR logs showed no indication it was even trying to record. I switched over to the non-beta client and tried with it. Same result. I am able to watch the channel live just fine, it just won’t record from the guide. I submitted logs from the non-beta client.
Edit: I think I figured out the issue. It tried to record this yesterday and failed. So I guess this is a request to allow re-recording a program that has tried and failed to record in the past.
That’s probably one of my top complaints. If I manually click on a show in the guide and select record, I want it to record that show no matter what. I don’t like that I may have attempted to record it 2 years ago and it failed so now it won’t let me record it unless I open the web based UI and find it in recordings and check the re-record button.
I’m cool with this behavior on passes but if I manually select a show to record, it should record no matter what!
Just adding some quick feedback:
As I've been playing around with the beta, I also kept thinking the same thing as I rarely change my guide from its setting (favorites) and have inadvertently changed it a few times while navigating back over to the left menu bar. The devs might have already considered this but two ideas came to mind: these guide categories could be moved to the top of the screen, which would then match the layout of the "On Now" section. Or maybe they could be put into a drop down menu like they are on the FireTV client. It's a good amount of space on the screen it could free up.
But otherwise lovin' the beta so far!
Is anyone else get any studdering while watching 1080i with any movement with content from the DVR? It gets better if I change the ATV to 4:2:0 output. Doesn't happen on my Android TV.
I think it might be only with 1080i content that is filmed at 24fps.
Changing the player to Blend seems to help also.
Changing surround sound to off also seems to help.
It's intermittent which doesn't help.
Since the iOS app is getting some love, can I make the appeal for the ability to make volume changes without the entire display coming up and blocking most of the screen? 
We hate that too. There’s plans to update the iOS video player UI, but it will probably come after this 4.0 ship.
I was fiddling around today and noticed that when using channels on Apple TV when I try to “Test Surround Sound” I just get an activity spinner for a split second and then nothing. I’m pretty sure this used to work. I’m trying to figure out if I changed something on my system that broke this. Is it still working for others? Broken on beta and production versions of the tvOS app for me.
tvOS: When a show ends, what is the expected behavior? I just get a black screen. Should it return to one of the main screens?
Just installed the update, and from here it looks amazing! Really well thought layout; even my wife was impressed. Thank you

Is this currently Alpha or Beta quality? I need to improve my WAF (Wife Acceptance Factor)
