Vizio tech support is working on it, as they are able to recreate the issue now, so I'll let you know when I get an update. however, for less than $200, we hooked up a Sony x700 uhd bd player to the pq65-f1 and it played both .mp4 in DV as well as the large .m2ts file (from the bdmv/streams folder of your backed up uhd disc) in DV. The .m2ts is better for sound as you get full hd-audio + atmos (with a 2nd hdmi out port for legacy AVRs), where as the .mp4 is lossy eac3 audio at best and requires demuxing / converting / remuxing. 3 confirmed Cinavia affected movies were tested using both formats from usb and dlna, and neither of them had playback stopped either, so hopefully that's not an issue (more testing is still required) :D
Unfortunately you cannot play .m2ts file in DV. I have just tried on Sony X700 and it played in HDR10 :(
Note that when you turn on DV in settings, even HDR10 video shows on a TV as DV.

I most certainly can :p what tv do you have? maybe double check all of your settings. load up a usb hdd formatted as exfat with a bunch of .m2ts files right on the root and you're good to go.

check it out:

m2ts from usb hdd: https://postimg.cc/LYzp1xq7
mp4 from dlna (plex): https://postimg.cc/ZWspMjCg
m2ts from dlna (plex): https://postimg.cc/gxj68RNK

the first two ways play properly. but as you can see in the 3rd link (m2ts from dlna) it triggers DV on the tv but the x700 says hdr, so not sure what's happening there and what to believe. but that's fine because dlna sucks on the x700 anyway as seeking forward and back is awful and playback freezes up from time to time etc, whereas usb playback is rock solid.

Nice! Could you try a few .m2ts files from movies with known Cinavia? I'm still trying to confirm if it's totally ok or not, just so busy though. I know there are programs like DVDFab Cinavia Removal, or DeUHD etc worst case, but it would be cool if no messing around was required :)

Just have to see which one's have Cinavia and I will be more then happy to test.

Just tried it with RPO and it reported DoVi with playback off a ext.

EDIT: I see what's happening. The TV thinks that it is DoVi due to Blu-Ray Player sending the DoVi signal but when checking the internal display it shows HDR for the .m2ts. I haven't tested it internal with a .mp4 but I believe that will work fine. So there will need to be converting.

weird I only get DV on tv but not x700 using dlna. external hdd shows DV on both every single time.. you obviously have dolby vision turned on in x700 settings so I'm not sure what's missing. what TV do you have out curiosity?

e55-f1. Tv won't play DoVi mp4's on the USB. Only reason I got the x700. DoVi MP4's do work perfectly fine on the x700, showing DoVi on both TV and X700. But yeah, the .m2ts shows DoVi on the TV since the setting is turned on (Think it's being forced since it is turned on) but in the top left corner of display it showed HDR.

ah the e-series. interesting. I have tried it on a pq65-f1 and it doesn't play mp4 over usb in DV either. yet mp4 works great on the x700. however m2ts works great as well. and the m65-e0 I tried does actually play mp4 over usb in dv no problem. haven't tried it on the x700 though, but I imagine it will perform as well as the pq65-f1 or better. seems to be a bit of a fw crap-shoot on Vizio's end whether it will work or not, depending on what model you have :/

People recommending the Sony X700 as a Dolby Vision media player should be a little careful.

It does correctly play back dual-layer DV if it is muxed into MP4 format, as described in this thread (meaning no HD audio). However, it doesn't play back dual-layer DV in M2TS format.

If you try and play a file like that via DLNA, it plays as HDR10. If you copy the file onto an external drive and connect directly via USB, then you'll get Dolby Vision output, but it still isn't actually reading the DV metadata from the file - instead it is simply reading the HDR10 stream and then converting that to DV on the fly.

The results still look quite good doing that (and if the M2TS file is only HDR10 in the first place then it will convert it to DV, and that can look very good); but it's not the same as actually using the dual-layer DV information in the file.

How did you get it for 140? It's showing 159 for me.

Must of changed since yesterday. When I purchased it, it was at $138 and change. I just checked and now I am getting quoted the price you just mentioned.

so forget mp4 for a second and just talk m2ts.
Even when both the player and the tv are showing dolby vision, it's still faking it? because that's what happens I play both a uhd disc and an m2ts from usb hdd. there's no difference I can find in any setting or menu or info display that is different between disc and m2ts usb. how is one to tell? I can see it being fake over dlna though, where only one of the two devices is showing dolby vision - as I said it seemed iffy, but I honestly can't see the dif with disc vs usb...

From that screenshot you posted a couple days back with playback of the .m2ts over USB it only shows the DoVi coming from the TV. It doesn't show it is getting DoVi from the x700. Can you please double check? Every .m2ts I tried (I tried a couple for sure!) only showed hdr10 from the .m2ts on the x700, but DoVi on the TV cause it was being converted as described by @shasarak

Ah ok. Sounds like it doesn't actually play dual layer DV anyway so not as interested!

"Fake" is rather a strong word, and somewhat misleading. The signal that it outputs is in Dolby Vision format, and will be correctly interpreted and displayed as DV by the television; it's a question of where it gets the DV metadata from. If you play a DV disc then it reads the second video layer and gets the DV metadata from there; if you're playing an M2TS file then it takes the static HDR10-layer metadata and repackages that as DV. What you end up with on the TV screen will often be exactly the same - the only difference is when the DV stream is varying the metadata from scene to scene.

Because the television is receiving a genuine Dolby Vision signal in both cases, you can't rely on the TV to tell you what the player is doing. If you want to see, press the Options button on the X700 remote while it's playing, and see what it says at the top left of the screen. If it's actually accessing the second video layer for metadata then it should say something like "Vision"; if it's only reading the HDR10 layer and converting it'll say "HDR".

(The ability of the X700 to convert HDR10 to DV on the fly is extremely useful, incidentally, especially if you own a 2016-issue LG OLED TV - the Dolby Vision processing is much better than the HDR10 processing, particularly for material with a peak brightness of above 1000 nits).
