Greetings, ma8785.
I see that you're seeing an error when you try to stream certain videos from your iPhone, iPad or iMac to your Apple TV. An Unknown CDM (Content Decryption Module) error has occurred and I'm happy to help.
If you can't use AirPlay or mirror your device's screen -- This article provides the information and steps that you need.
If the steps above haven't resolved the issue, please answer the following questions:
Let me know how that goes, and take care!
Whit the most films there is no problem. AirPlay is ok for 90%.
Some films ... no AirPlay possible. The most ok.
What do you think about this ... Digital Rights Management ( DRM ) on some films ?
is this possible ?
