How do I cast to more than one device at the same time?

[DB17]

I see my two devices but I can't cast to them both at the same time. Thanks for your help!

I am sorry, you cannot cast VIDEO to more than one device at a time.  That is not supported.

You can cast AUDIO (music services) to more than one at a time if you setup and use Speaker Groups:
