Ya, better go for BD.

4K BD 😜

Not that I'm aware of, no. I'm streaming off several NAS, no issues on my end. There's the occasional freeze when trying to load up a movie, but a quick reset usually fixes it.

I just hope the 203/205 players will be much faster in operation though.

Wow 4k BD I don't have any yet but just have some 3D BDs.

ID4 RSG!!! next haul!!!

This 4K BD is also 3D so is worth while to buy

U mean those 4K BD u bought above comes wt 3D BD as well??

Yes that is right

UDP-203 removed internet apps and using latest Quad core SOC, should be faster
32bit DAC either AKM or ES9038, HDR, Dolby Vision, DTS-X, Atmos

I only aware that certain 4K titles actually comes wt 3D BD as well but not all right? Correct me if I'm wrong.

Actually those 50gb file (dwled) compared with BD is there any difference in terms of sq & pq?

Yes not all comes with 3D and 2D. I am not sure those file and actual BD has any special difference

I see, maybe some sifu here can share their experience whether there's any difference on sq & pq?

So these 4K, Bat vs Sp & Xm Apcly comes wt 3D BD? This Xm, Martian, ID4 RSG and mostly new movies under 20th Century Fox, 4K version titles comes with D. Atmos but normal version BD only in DTS MA! This makes me wanna get 4K versions but 4K gears are still very expensive now!

IMO,

If there is any difference, its minimal..
But the ones l have seen are duplicated from a tru bd - dunno abt those dwnldd from the net ones..

Thank you FYI bro! Anyway Nice BD collections you've got there and I think you've collected many 4K titles!

Stilo10 was talking about (1) Dolby Atmos in 4K 3D Bluray and (2) DTS-HD MA in 3D Bluray. When anyone talk about 4K bluray, we don't need to ask about PQ because all of us obviously know that 4K with 1080p X 4 resolution and HDR wins! Since the PQ answer is already known by everyone, its now about the SQ between 4K bluray and regular Bluray. SQ ?... No difference loh. Read my answer to Stilo10 below about the SQ.

At the present time, ripping (duplicating) a 4K bluray is not possible because AACS 2.0 have not yet been cracked yet. Yes, you can "duplicate" from a actual genuine 3D bluray, NOT for 4K bluray. Actually I do have a question to ask you.... Have you personally watch 3D from an actual genuine 4K bluray (with HDR) ? Is the 3D more realistic and better colour rendition in 4K 3D blurays compared to the regular 3D Blurays? I have seen 4K blurays but not 4K 3D blurays. I am curious about this.

Any comparison between 4K Bluray and the 1080p Bluray is actually about the improvement on PQ only. Its not about SQ because both the 4K BD and the regular Bluray can both use DTSMA, DTSX, Dolby TrueHD, Dolby Atmos, Auro-3D and whatever. If they follow the same audio standard specified by DTS, Dolby and Auro, then no difference in SQ so its NOT because 4K Bluray audio being better than the regular Bluray loh.

Similar question can also be asked about comparing a movie (example Bat Vs Sp) SQ in a regular Bluray sold in Europe with DTSMA and the same movie in another Bluray sold in US with Dolby Atmos. Therefore, no one can give any definite answer on which SQ is better because each bluray audio recording and encoding is different.

Just for the sake of discussion, I assume that Dolby Labs came out with a "special" audio type called "Dolby 4K-Atmos" that will ONLY be used for 4K Blurays, and more superior and better to Dolby Atmos... then I can safely say that such SQ in 4K Bluray is better than the regular Bluray.

Obviously people want 4K blurays primarily because of the PQ with 2160p and HDR. Any comparison for SQ is not the reason for choosing 4K Blurays. IF... an audio type better than Atmos, DTSX and Auro-3D is released that is only used in 4K blurays, then its a huge bonus and only then that people buy 4K blurays for the PQ and SQ.

DVD audio only have PCM, DTS and Dolby Digital audio but ONLY Blurays have DTS-HD MA, DTSX, Dolby TrueHD, Dolby Atmos and Auro-3D. So obviously the Bluray SQ will be much better than DVD. IF, I say IF, DVD can use also the same audio type in blurays, then there is no difference loh. When BOTH 4K Bluray and Regular Bluray can have all the same audio types, we just cannot make any SQ comparison.

Tq Master James for your detail explanantion but my question was actually on comparing the difference between normal original BD (not 4K) and those dwnldd file like ISO & etc. around 50gb for sq & pq. Sorry if my question was unclear.

An .iso is an image of the raw blu-ray disc. No difference except one is a soft copy the other is a hard copy.
However, there exists several different releases of any single movie and there can be differences in them as they are mastered differently in the studio.

Comparisons here - http://www.caps-a-holic.com/index.php


A remux file is basically the entire .iso image put into a container (like mkv). But generally remux do not have any of the "extras" to save a few GB worth of space. Remux IS equal to an .iso/blu-ray physical disc in picture quality and sound quality.


Then we have all the million and 1 infamous re-encodes, rips, and blah blah blah. There exists many groups which really put a lot of time and effort into getting their encodes right. Groups like FGT, PTP, SCENE for example do release great rips.
Unless you are super anal about even wanting to complain about a hair strand looking different, these groups usually release their rips with about 90-95% of the PQ from a .iso/physical disc. Bonus of course they pack them with lossless audio tracks, which again is entirely the same with the one on a raw file.

Of course... there exists idiots like yify or whatever, those butchers quality more than youtube does.

Regarding 4k BD vs 1080p BD, picture quality wise... it really depends on how the movie is shot. Right now, the majority of 4k movies on BD were shot with 2k cameras, digitally.

Watching Mad Max Fury Road in 4k is actually a little worse than watching in 1080p, simply because CGI effects like the flames and storms look very cartoonish as it is artificially remastered into 4k from its 1080p source. Just a simple example.

But then we have movies like X-men Apocalypse which is MIND_BLOWING in 4k + HDR itself. Completely rapes the 1080p version in PQ twice over.

Speaking about the soft copy vs hard copy of the same source and same system, some one told me that SQ of a Bluray disc is better than streaming .iso from HDD. Is that true?

Yeah nowadays new movie mostly come out with the older sound format unless is 4K. Movie maker is trying to encourage movie goer into 4k

Hehe... when you said earlier "...share their experience whether there's any difference on sq & pq?" and then you wrote about 4K without saying anything about BD ISO, then this caused the confusion. Anyway, no problem.

Bluray ISO is a one-to-one 100% image copy of the actual bluray disc without any loss of data. Playing the BD ISO has no difference compared to playing than the actual bluray disc itself because the data read by the player is exactly the same.... BUT.... yes, there is a BUT here... somehow there is some difference for me... there are people who can hear the "subtle" difference and there are those that hears no difference! Why do I say that ?

In my personal opinion, eventhough BD ISO has the same data, playing the actual bluray disc sounds better !! Here are the possible reasons that I believe can cause such difference...

1) The longer the path from source played (bluray) to reach the AVR and TV, the more chance there will be that "interference" can interfere with the signal such as EMI. The BD ISO has to be stored in a harddisk which do have moving magnetic discs spinning by an internal motor which can cause interference... and then the USB cable to the player which can also be a problem too. Using a SSD harddisk with any motor will help. The player using laser light to read directly from the disc has the shortest path.

2) When additional hardware is used such as NAS Network Enclosure, Ethernet and WiFi Network is used to "stream" to the player, then quality should also be affected.

3) The desktop computer is BIG source of all sorts of "noise" so if a HTPC is used to play the BD ISO, then quality will also suffer!

4) When additional AC/DC Power Adapter is used, it can also cause interference too. Example... adapters for harddisk dock, External NAS Harddisk, NAS Enclosure, WiFi Router etc.

Knowing this, that is why there are people who uses Notebook SSD (Solid-State) harddisk, good quality USB cable, Low-Noise Power Adapter and so forth. I did all this BUT because the signal path (highway) is longer, I somehow still prefer playing the actual bluray disc. Its NOT because of any "lower quality" from the Bluray ISO itself.

Retouched And Remuxed Bluray
This is where the quality CAN suffer when the actual bluray disc data is changed!

A BD50 bluray disc can store a maximum of around 50GB. It doesn't mean that a movie used 50GB. If a movie is originally encoded to 23GB, then a BD25 disc is used so ripping this to 23GB ISO will have the same quality. But... if a movie used 43GB and it is ripped to a 23GB ISO or duplicated to another BD25 disc, then the quality will drop.

A remuxed bluray can mean these things...
(1) When the disc is ripped, all the bluray menus and all "Special Features" and Trailers are removed so that the bluray ISO (BDMV Folder) plays the movie instantly. If they did NOT touch anything to the actual bluray movie file, then the quality will be the same. Whenever the bitrate or filesize is reduced, then quality will drop.

(2) The bluray can be remuxed to a single file such as MKV, MP4, TS, etc. Again, if nothing is touched and transfered to the single file, then quality will be the same BUT most of the time there is shrinking done which also reduces quality. Examples... 35GB bluray remuxed to to 10GB MKV, DTS-HD MA becomes DTS, Video bitrate reduced.

The most important factor whether the "duplicate" has the same quality as the original is actually knowing whether its an "untouched" copy or any "touching" have been done to it. Whether quality will be the same depends on whether anything have be touched on the original... not about ISO itself.
