... 2 are separate devices hooked to 2 separate TV’s .... stopped about the same time. ... “Unfortunately, an error during playback. Please try again.” ... “Protected content license error.” ... audio but no video.
For two separate devices to stop working at the same time, there is either a huge coincidence, or something in common. Two things that come to mind are power and network. However, I'm not sure how they would cause what we're getting.
Lightning could have surged on the power system enough to cause issues, but I've nothing to base that on.
Another possibility could be network, as those two devices have a common limitation of only being able to connect on 2.4 GHz band. The Roku TVs are dual band, and could be connected to 5 GHz network.
Usually, this issue manifests itself as no connectivity at all, although there have been various levels of connectivity reported. This will be easy enough to rule out if you're willing to do a check.
If your wireless router is supplied by your ISP, note that some major ISPs (Comcast, AT&T, others) have begun changing the 2.4 GHz settings from 802.11 b/g/n to g/n. If you can check your wireless router settings and see if this may be the case with you.
Others may have some better suggestions, or my musings may strike a memory with you about something seemingly unimportant now coming into play. Try checking the settings and see where that leads us.
