JRiver freezes when loading BD menus
« on: June 29, 2022, 01:14:16 am »

Hello.  Windows 10 install... Blu Ray ISO's and BDMV folders play just fine, but when I try to launch the Blu Ray menus JRiver freezes on a black screen.  Have to force quit through task manager.  Searching didn't reveal a solution so hoping someone can point me to a solution.

Thank you.

When you play a BluRay with menus for the first time, MC is downloading java64 and libbluray64 and places them in your "%APPDATA%\J River\Media Center 29\Plugins" folder. Check if you have them. If they're not there maybe something is preventing MC from downloading them.

If you have them you can remove them just for a simple test and let MC download them again.

MC sometimes doesn't work with a BluRay in menus mode if the region of the BluRay is not the same as the Blu-ray Region Code in the MC settings.

Also, check if you don't have JAVA_HOME or JRE_HOME defined as user environment variables. I don't know if the libbluray bundled with MC is modified to ignore them. If you have them, then you likely have "C:\Program Files (x86)\Common Files\Oracle\Java\javapath" or "C:\Program Files\Common Files\Oracle\Java\javapath" added to your PATH system environment variable as well. This means a different Java installation on your system will be used instead of the one that comes with MC, and that version of Java might not be supported.

Thank you for the suggestions.  I have two identical PC's both exhibiting the same behavior.  I have a third more powerful machine, with which BD menus work fine.

Both java64 and libbluray64 are in the "plugins" folder (on all 3 machines).

There are no oracle folders under the /common files folder (on all 3 machines).

Are there any other troubleshooting suggestions?
