As usual, I have a new idea in my mind... but before disclosing it, I need your help!

MANDATORY:

• an UltraHD Blu-ray hardware player that can read files written onto BD discs
  
• a BD disc to "sacrifice"
  
• some time to make test - I guess an hour at most
  

OPTIONAL:

• a real 2K/4K display or projector - https://fanrestore.com/thread-4372.html
  
• an hardware media player - or the ability of the player to read files from an external USB memory/hard drive
  

What do I want to find out?

I'd like to discover which kind of combination an UltraHD Blu-ray hardware player is able to play from a BD disc:

• resolution: 4096x2160, 2048x1080, other 2K/4K
  
• video bitrate
  
• audio frequency: 44kHz, 48kHz
  
• audio channels
  
• container: mkv, mp4
  
• video codec: h.264, h.265
  
• audio codec: FLAC, PCM
  

REWARD:

• access to real 2K/4K - mainly trailers, but also some documentaries
  
• my endless gratitude!
  

I read online (on some forums and actual manuals) about the fact that some players are able to play such kind of file, but it's not clear in which combination; so a proper comparison would be more useful IMHO.

If someone will chime in, I'll use a full 4K 4096x2160 source and I'll encode video and audio in different "flavours"; what you should do is to burn the files on a BD disc (25GB will do) and play it on an UHD-BD player, and note which file plays perfectly, which with problems (like only video, only audio ect.) and which does not play at all.

As optional test, to know which media (or UHD-BD) players are able to read the same files when written on an USB memory/hard drive.

Thanks in advance to any volunteer!

I got a player but on ways of burning a disc anymore but it does play files from a HDD so happy to test those if you want to send them over

Thanks! I'll wait first for someone who can actually burn a BD.

I have an UHD player, but I am not sure if he can read from data BD. He is very basic. I have some empty double layer BDs to spare and am able to burn.

I'll try to burn some mp4 to a disc later this evening and pop it into my player.

What model is it? IIRC even basic Panasonic players could read files with (up to) 4096x2160 resolution.

It's a Panasonic DP-UB154EG-K

Somehow my burners are killing all BD-Rs I tried to burn so far...

According to the manual (https://cdn.cnetcontent.com/de/61/de619a...a0c994.pdf page 33) it can play 4096x2160 files...

Burning: have you tried to burn at slowest-speed-as-possible? What blanks are you using, Mediarange?

I killed 5 Verbatim BD-R DLs so far with different speeds, and tried two different burners. One is a Pioneer USB, that should be able to even burn BDXL... (Pioneer BD-RW BDR-XD07U) the other is a downgraded LG that is able to at least read UHD BDs...

I don´t have a UHD Player anymore, but at the beginning at this year i had an Panasonic DP-UB824EKG. Tried to play a burned UHD blu-ray BDXL (with DVDFab UHD Creator), but the player couldn´t read it. Burned at slow speeds with the famous Asus BW-16D1HT.

What about BD-25 discs? Do it work(ed)?
