Does the HR92 display it's firmware version anywhere, either on a sticker or on start-up. IMHO Resideo actually do not handle part numbers very well, the latest BDR91 is quite different from the old BDR91 and yet they are called the same. I try and force myself to refer to the new ones as BDR91T.
So although the latest ones might still be called HR92, it could easily be a newer hardware and software sitting within the same outer shell.
