4K/UHD bluray players that decode DTS to Dolby?

With 4K bluray players starting to emerge now, seems we really need to start keeping straight which ones will allow those of us with Sonos Playbars enjoy some semblance of Dolby sound when certain 4K blurays only offer DTS. (Note, I haven't yet purchased a 4K bluray, so am unaware of the typical sound offerings.)

But we went through this once already, for regular bluray players, with many threads devoted to outlining the multiple Samsung models of bluray that decode DTS to Dolby 5.1 (I ended up buying a Sony that also does so). Now let's do the same for 4K players.

So far we have the Samsung UBD K8500 (which seems to clearly decode DTS to dolby.) Now what about the Philips? The Panasonic? The Xbox One S?

Anyone have any idea?

Hi, everyone. I've been looking for a decent feed regarding this issue with transforming DTS to DD5.1 and this has been a brilliant read. I'm not totally at ease with the technical terms etc and what's required but I use the Samsung 4K KS7000 TV which doesn't support Dolby Vision. So my questions are, does the Xbox support the encoding from DTS to DD5.1 and is it a better UBD player than the Samsung. I'll be honest that I can't afford the Obbo 203 but which other unit should I buy. I really need help as most of my current collection is format DTS and not having proper 5.1 sound is so frustrating beyond belief. I desperately need to transform DTS to DD5.1. Please help........thanks

If you don't need Dolby Vision, then your choice of a player is simpler. The Xbox One S is supposed to transcode to DD5.1. There was a post in this forum where someone even posted the menu steps to enable it.
I considered the Xbox before I got the Samsung K8500. But since I'm not a console gamer, it didn't seem to make sense. For one thing a white box was really going to stand out sitting under the TV while everything else is black. Plus, you have to download a blu-ray player app from the Xbox store and then configure it. Then, the game controller doesn't make a very good movie remote, so you have to buy another remote for this. Like the Samsung, the reviews of the Xbox as a Blu-ray player were so-so. The Samsung just seemed a less complicated solution.

To be honest, after testing out the Oppo 203 today, as far as picture quality I saw no difference. Maybe if I had identical screens side by side I might see something. But, I'm quite happy with the Samsung. I bought it from Costco because they have a 90 day return policy. So when the Samsung M8500 comes out soon and lets say it has Dolby Vision, I can have the option to upgrade.

I've been testing the new Oppo 203 player. Unfortunately, with my configuration I don't think it's going to work out for me. My setup is the STB and the Oppo connect to the TV's HDMI ports. The TV's optical out port goes to the Sonos Playbar. This works very well as my TV passes DD5.1 out the optical port. What I didn't realize until I setup the Oppo was that the DD5.1 transcoding they just added was just for the player's S/PDIF port. Not the HDMI port.

D'oh!

So, I experimented with the Oppo's HDMI audio settings. Here is what I found:
If the movie is in Dolby True HD then setting the the players HDMI to use Bitstream resulted in in DD5.1 to the Playbar.
If the movie is in DTS-HD then I get no audio unless I set the players HDMI to use LPCM. In which case the Sonos app states "Audio in: unsupported" but I get a pseudo surround effect. It seems to be similar to Pro-Logic Surround which is not a true surround. When I watch a movie in Dolby True HD with the player's optical connected to the Playbar it sounds much better (the Sonos app then shows audio in as DD5.1)

So, the only solution for the Oppo I see is to use an optical switch, to switch the Playbar between the TV and the Oppo. But that's a pain.
The Samsung just plain worked with it's transcoding as it also sent DD5.1 out it's HDMI port. So, given that the picture quality seemed just fine with the Samsung, I think I'll have to forgo future Dolby Vision support with the player and return the Oppo.
Sheesh.....
Tom I'm not completely clear how most would take advantage of the transcoding then - aren't most people's set-ups like yours? e.g. working through the hdmi port? Mine certainly is! Why would they assign this audio feature to benefit only through the S/PDIF port? This info is appreciated though, and is a deal breaker for me - along with another issue in my case - my designated shelf in my entertainment center can't fit this player! The player is too wide by about half an inch! UGH. All roads keep leading back to the Samsung for me.

I agree Carson. I had assumed Oppo would have implemented this like Samsung did and have the transcoded audio go out both HDMI & Optical. Maybe they didn't see this as an issue since all soundbars except the Playbar have multiple inputs.

The Oppo was a nice player (lots of menu option and output ports) but it is expensive. Right now, I'm happy with the Samsung. It has great image and sound quality. In the future if the lack of support for Dolby Vision becomes an issue I'll have to re-evaluate the situation. Since Dolby has stated there will be a software-only version soon, I think a lot more players will have DV (hopefully the Samsung M8500). So, I'll think have some viable choices.
But, as I stated before - don't wait too long. You're missing out on some spectacular image quality. If you get the chance to watch Hacksaw Ridge in UHD HDR - the early scene with Hugo Weaving in the cemetery is jaw dropping gorgeous. Had friends over and they were totally amazed when I showed them this scene.

Alright Tom. I can't find the feed for the Xbox setup. Want to make sure before I take the plunge. It's really complicated isn't it haha. Do you know where the link is mate. Still pondering which one to get. Obviously I don't need the Dolby vision but obviously DD5.1 and HDR is a must. What's the quality like on the picture does anyone know?

I can't find the link. But I did do a cut & paste of his instructions in case I ever needed them. Here is what he posted:
Xbox One DD5.1 setting:
All Settings > Display & Sound > Audio Output
Set to:
HDMI audio: Bitstream out
Optical audio: Bitstream out
Bitstream format: Dolby Digital (other option is DTS Digital Surround)

Hi Opsman...I did get the Oppo, for a second time.

I installed the beta update and, yes, it decodes to DD beautifully. You change the audio output option to optical and select the new option to send the signal as Dolby.

However, tom12 is correct in that it works only via optical. To avoid swapping out my optical cable from tv to Oppo everytime I watch a bluray, I chose to order a $20 optical switcher. This is slated to arrive tomorrow.

I'll connect my cable box and Oppo via hdmi to my tv. Then I can connect my tv optical out to the input 1 of the switcher. I'll connect the Oppo optical out to input 2 of the switcher and the optical out of the switcher to my playbar. When I watch the Oppo I just need to switch to input 2. It has a remote. You can also buy automatic switchers but I'm fine with switching it myself. Plus, with Oppo's track record, I'm guessing they'll implement this feature via hdmi in a future update. The functionality via firmware updates just keeps getting better.
