The only way I can see to do it with the information available is to use a momentary switch and do it manualy. The switch would tell the PIC to skip lines until the VBI bar is hidden and when the switch is released, the picture should stay stable until it loses lock. This would require removal of the check lock code in the MakeVBI and modification of code in the Main routine for skipping lines.

If there is any identifying characteristics that are repeating in the VBI, then that can be used to locate the VBI. The code could also be written more like the Maxi* code where it looks for a hsync pulse and if it doesn't see one, it assumes that the VBI is starting.
