I've been buying Blu-rays through the Crunchyroll store and up until last night haven't had a problem with region locking. I am in Australia, but the player I have lets me change the region it is set to so I've been able to play USA locked discs without problem.

Then, last night, I tried playing "The Ambition of Oda Nobuna". I got a message saying it was region locked to the USA and Canada then it went to a black screen. I tried again and it still didn't work. I tried changing the region on my Blu ray player and it still didn't work. I decided to try another Blu ray I bought recently - "My mental choices are completely interfering with my school romantic comedy". It had the exact same problem. Both were released by Sentai Filmworks so I tried another, older Blu ray from the same company and it worked just fine.

Has anyone else had a similar problem with these two releases? Has anyone else from outside of the USA got these to work on a different Blu ray player that can bypass region locking?

some Blu-ray players have a limited number of times they can be changed. So if you have been changing the region its possible it reached its limit and thus is unable to be changed back into US region.

also not all blu-rays (both movies, as well as players) are region locked, so are you sure the older bluray that you tried has a lock on it?

Also, some blurays have hidden locks that arent just about the 3 regions. (Region A includes america's and japan and some of the philipines, yet not astraulia (which is region b) yet some region A have hidden locks that prevent them from being viewed in areas not listed to prevent reverse imports back into japan at a cheaper price (check the box to see if it has something like


also, try the method listed here

My understanding was the devices would allow like 5 different region unlock changes before being locking finally onto that 5th region. Something near the hardware level on the player. If it was software that noted the changes, I am still not sure what file would be doing the locking. It is like a 60 day microwave warranty that at 61 days the microwave breaks down and you have to get a new one.

I've no idea when the release date was. I preordered it through the Crunchyroll store and it arrived a week or so ago (I forget exactly when).

I don't think the player has a limited number of changes, even if it did I've had it set to region A up until last night since I bought it.

I tried that method to get around the lock, it didn't work unfortunately. Thanks for the suggestion though.

Unless you put hacked firmware in it, you only get five region changes. If you put a protected region B/2 disc in a player the first thing the firmware does is check whether the drive is region locked and if the disc region matches the current player region. If it's not region locked it decrements the allowed region changes and allows you to continue. The way to unlock is put hacked firmware in it.

Wouldn't that depend on what Blu ray player you have? Mine is this one: http://www.laserco.com.au/BLU-BD1000

The option to change the region is in a "hidden" menu (the button presses to make it appear is listed in the manual).

as a multi regional bluray player. you shouldn't have to change the region at all. but the ability to change regions is limited for all players I believe, just dont think it'd matter on that specific model whether you changed the region or not.

not quite sure how sentai goes about hidden locking of the regions. that post I got the link from mentioned that it was only meant to limit region A from being viewed in japan (which is also region A) to prevent reverse imports. not that it'd stop you from region changing a player to A to be able to play it. so. its possible that his bluray player was locked into austraillian region (which is b) and isnt able to be changed out of it now.

older blu-rays didnt have the hidden lock on them, and some dont have a lock at all. so it really depends on what his current setup is. since I dont see how his bluray would be set to A, yet not play A blurays its possible its locked in B, since unless its connected to the internet there isnt much other way for it to automatically detect where its located.

As I understand it, Blu rays have 3 regions - A, B and C. In order to play a disc your player must have the same region set on it. DVDs also have regions, but a DVD player can be set to region 0 which will play any DVD regardless of where it is from. Blu rays don't have a region free setting supposedly, they can just be multi-region letting them be changed at will.

I'm guessing they have some means of protection beyond the three regions and my player can't handle it because it doesn't match up with that as well. I can change the region at will in order to match any given disc but it seems I need something more.

I suppose I could import a Blu ray player from the USA and get a power convertor. That's a bit of a pain though. I've emailed the company who made my player and I'll see if they have any suggestions.

there are some blurays that are region free (Due to modding of hardware/firmware), and others that are multi-regional. yet most are region locked with the 3 main regions. Since the multi-regional ones require the regions to be changed (Guessing thats the kind you have) its possible that it isnt enough to bypass the hidden region lock in place,

sentai seems to place a hidden lock that limits region A to only US/canada, not sure how they do it exactly, so that might be whats causing your problem. since it probably looks for a hardware type thats only used in US/canada players, which would prevent any player from playing it even if its set to region A, to prevent japan players to be able to use the same trick.


have you tried the title search method in the thread I posted before? it mentions that it usually works on sentai blurays. also mentions it has to be done quickly. (also seen some threads say that for step 2, it has to be done before the region lock screen appears, so could try that also)
Insert the Blu-ray disc into your Blu-ray player / console
Once the Region lock screen appears select the “Go To / Title” option (it differs from player to player)
Choose title 5 (sometimes 4) and press OK / Play / X button
The first episode (if a series) will start playing in it’s default audio language
Press the pop-up menu to view the overlay menu and choose items as you desire

I tried the title search trick but it didn't seem to work for my player. I do have a PS3 as well, but I kind of doubt Sony would leave that kind of exploit unpatched.
