A couple weeks ago, Oppo issued a firmware update that broke the default method of IP control. We have provided them with the necessary information to resolve.
In the meantime, if you are having trouble controlling a 10X model of Oppo BD player, we recommend switching to a method of control we didn’t announce but is in fact already in all editions of Simple Control. Add the unit via Manual IP on port 436 and select the “Media Control” category. That method is actually more functional than the default method. Until we fully certify this new method, I’d recommend switching back to the default IP control when the original IP control is fixed by Oppo however.
Thank you.
