Finally figured this out. Here’s some help for the next guy! Download the codeset from above to your iPad. To add your new JVC projector manually, you’ll need to go into settings, then custom devices and click on import custom device to import this code into the app. Find where you saved the .plist and import the code. Then you add the device manually and look for the JVC projector that is “IP Hashed” on your IP, at port 20554. Hope this helps someone else. It took me awhile and some help from Will and Support. Thanks so much!
