Hi Bob,
that smacks like a problem with the Virtual Aviation MCP, then. I am not familiar with the device, so I can´t tell you about any problems or pitfalls with it. Maybe there is a dedicated support forum or you can open a new thread here that is aptly named (maybe in the cockpit builder/hardware subsection) - there are some more knowledgable people around that may have an answer on that.
To make a video, you can use the built-in movie-maker in X-Plane, it saves the quicktime movie in \Output. But those movies grow quick in size...
Cheers, Jan
