Would it be very difficult to duplicate this in VDR?  I would love to start
trying out code. My programming skills are just not good enough to start
implementing this task. But, once there is some framework, I can get by trying
things out.

What if the reception goes out for long periods of time and the sync becomes
really bad?  The firmware must have more limitations than a software solution?

Best Regards.

N.B. Thanks to everyone that is looking into this further!
