A:AnswerFor 4k movies, its worldwide unlocked. For blurays and dvds, the region specific movies will still apply:
"When it comes to regional restrictions, the good news is 4K Blu-ray discs have just one region code: worldwide. Essentially, they’re region-free. They can be played on any 4K player, in any part of the world.
However, your new UHD Blu-ray player will still have to observe the regional restrictions for DVDs and standard Blu-rays that continue to exist."

A:AnswerI could find nothing in the manual regarding regionality. However, I own one disc from France (region 2) which plays perfectly on this machine. I have no other discs to try.
A:AnswerI didn't think so but, your question prompted me to pop in a French disc that cannot be played on my other players and it had no problem. No adjustments were necessary. As that was my sole non-North America disc, I haven't been able to test any others. The manual makes no mention of region.
Excellent upscaling on my regular blu-rays! Very impressed!
A:AnswerCheck updates by going to the update menu on the player. Some movies require updates from the firmware. If they are bootleg or from a bad source, the dvd's might be defective. It happens.
A:AnswerI never use the player as an streaming service, cause the Roku Ultra does a phenomenal job as a streaming box. So if you find yourself doing more streaming than playing discs, i would stick with a player that only does streaming and nothing else. Although my tv does a better job that Roku, Roku is still OP.
