Recording video in Minecraft while the Groove app is streaming music appears to break the ability to capture the video correctly. What I end up with is a video of the Worlds/Realms screen with glitch mice cursors all over it and the Groove music in the background. I've been able to record video fine in the past without Groove playing. DRM issue maybe?

This isn't an issue with MCPE. It's probably the recording application or some other software that's the culprit.
