I think there are two stutter issues though.
The one above, fixed, and a micro-stutter issue at 23p reported by @markswift2003
(I think we are equally sensitive to it).
Maybe he could comment and let us know if it's fixed, both in 2D and 3D, and if it's both on BDMV and mkv or just on the latter?
Hey Manni, nice to hear from you,
As you rightly say, I now rip with MakeMKV to .mkv only and remove all the streams I don't want (subtitles, extra audio etc) so I'm left with a simple remux with Video, Audio, Subs for foreign parts (I hesitate to use the word "forced" although I do set the default and forced flag on them) and chapters.
If I deem the film worthy, it will remain as a remux on the NAS drives. However, on many films, once I've watched it, I'll then encode it with StaxRip (I've set up a dedicated encode PC which will encode a UHD Remux in hardware in about 45 minutes and I can get a say 60gig film down to say 25-30gigs with no discernible drop in quality).
I'm afraid I haven't tried any BDMV rips, but since it's the same file in a different container, and in the case of BDMVs, several containers, I would expect MKV to perform better. That's logically at least, and I appreciate logic rarely translates to fact in this world! So at some point I must try a BDMV rip.
Also, I'm afraid I don't use 3D at all, simply because I don't like it.
So as far as micro-stutters and file bitrate goes, in my case, whether the file is a 60Mb/s remux or a 30Mb/s encode seems to have no bearing on the stutter.
I don't believe it is my network which is gigabit - 4 Netgear Prosafe managed hubs as a backbone and several Netgear Prosafe "dumb" hubs on spurs, and the route from my media players to the NAS drives is though a single managed hub.
I don't believe the problem is HDMI - although my HDMI between Amp (Denon 8500) and PJ (JVC 7000) is 15M and 12 years old (!) it will pass 12-bit 4:4:4 at 4K23 (450MHz) without batting an eyelid - I used to own rather a large company doing both domestic and commercial large scale installs and we used to regularly use 60M HDMI runs (made by the same company) all the time - admittedly this was in the 1080p days, and I've always wondered when my cable will bottleneck, but it just hasn't happened yet.
What has made a discernible difference is switching protocols from NFS to SMB. I read something a while ago on another forum - think it might have been a Zidoo one, and it's something I'd never considered before given the lack of overhead and brute simplicity of NFS. However, I tried SMB and it made an immediate difference.
So remember I said it's one of those things you're not quite sure you see, but if you have to ask yourself, then you definitely did, well the instances of "did I just see that?" have diminished to the point that I almost want to use the Dune over the Shield (on which I've NEVER seen a stutter btw!).
So on to the last firmware update.
Firstly, I was bitterly disappointed with it, particularly after such a long wait.
Ok, they've made inroads into BD menu, but they haven't addressed more fundamental problems -
HDR SEI messages still persist into menus (won't affect everyone I know)
HDR to SDR is still the same - gamma is way off - about 0.6 in my estimation, so unless you can apply a gamma curve of 1.6 (you and I can!) it is unusable.
Skip+ & - still don't work - there's no excuse for that!
IP control is rendered useless because standby still disables the network card (I have a nasty feeling that's a hardware restriction though) - I know a hybrid solution is easy enough, but it's just not elegant.
It still clips black - from memory, I think it was at 2%
And micro-stutters - I'll be dead honest, since the latest firmware, I've been using the Shield to stop becoming annoyed at the Dune, but I will use the Dune to watch my next film and let you know.
Anecdotally, I did watch T2 Trainspotting the other night in the early hours on the Dune and I did not notice any micro-stutter. I was however, extremely drunk, so that observation cannot be relied upon.
