Video calibration message on JVC S-VHS?
 

During some of my streams the video slightly cuts out and I see a message appear saying "Video calibration" overlayed on top of the video. This message gets saved into my stream. Is there a way to disable the message from displaying? Also, how can I confirm that my external TBC is actually working properly as this seems like this is the internal TBC kicking on from the VCR?

This is the lights on for the external TBC. I'm assuming it is fine based on what I've seen in the manual.

Disable on-screen overlay in the menus, using the JVC remote.
