Solution?

1. Hand-edit every frame to line up the edge again.
2. Write some software to fix it.

36.4.6 Ghosting

Ghosting (Figure 36-7) is caused by analog signals reflecting from another surface and
arriving at your antenna somewhat delayed with respect to the original signal. Wet leaves
on trees and large buildings may cause this. It is theoretically possible to remove ghosting
effects using sophisticated image-processing techniques, but in practice it is hard to deal
with. Sometimes it's just best to wait and record the program at a later time.
