How to remove UOP (User Operation Prohibition) from Blu-Rays?

[DreckSoft]

I'm trying to remove UOP from a BD but so far no luck. I tried the Blu-Ray Region Remover 2.5 but it didn't change anything. I assume it is possible with BDEdit but I don't know where to start.

I added some audio tracks to a Blu-Ray I own and wanted to keep everything else original. So I muxed the audio tracks with TSMuxer and replaced the m2ts and the clpi file. Unfortunately I cannot change the audio track using the key on the player. The orginal BD only had one audio track and the switch function seems to be blocked.

The attachment show the commands for the main movie
17620

The first line sets the default audio track to the original one (I think) but it should not prohibit changing it. Anything I'm missing?

AnyDVDHD can remove UOPs from Blu-Rays while ripping the BD to your HDD.

Yeah but it seems to be the only ripper who does that (MakeMKV and DVDFab won't) and I'm not planning on spending 110EUR for a license.

They offer a trial period...

Yes, that would solve the issus with the BD I have right now but learning how to do it properly will solve it forever ;)

Thanks. It seems the Blu-Ray Region Remover 2.5 DID clear those flags.

I just realized that the current issue is a different one. The audio streams are also stored in the PLS file, so I need to add them there: I din't copy over the PLS file to preserve the chapters. After adding the audio tracks, switching worked.

Strangely I still cannot skip the "FBI warning" besides all UOP flags are cleared.
