Today (April 29th's) Blu-Ray Player Update does not allow me to play discs anymore

Have you tried disconnecting the hdmi cable from both the xbox and the tv, power cycling both the xbox and tv and plugging it back in? This should reset the connection/handshaking.

Edit to add:

I updated my app and put Deadpool in, no issues... except now I'm up at 1am watching Deadpool.

Xbox One supports 3D Blu-ray discs when played on 3D TVs. Try checking whether there are any updates for The Blu-ray player app

@dude, I think they say that cause your not allowed to comment about future hardware the other person may have not known and said it out. but lets all ask our selfs this...a blu-ray player plays blu-rays regular or 3D why would Xbox one will be to only Blu-ray
player on the planet that plays regular blu-ray? regular blu-ray and 3D blu-rays use the same disc fame format just written diffrently on the disc but both can be picked up by the same laser, yes yes, and yes It plays 3D movies and games

its the update that *** up things. blu ray players have to be constantly be updated because the code writers for the discs continually keep changing the read code to combat piracy.

MS does NOT spend the time necessary updating the blu ray codecs and security protocols

that only partially works. what needs to be done, which is what I did....

delete blu ray player app. delete/uninstall the last game and updates that you downloaded.

do the steps above.

make sure to use a disc to REINSTALL your game FIRST. this will force the disc drive to recognize blu rays again.

then try to play a blu ray movie.

should work after that. did for me, anyway
