Hi Gabriel-

Great find! I think you had a good bit of beginners luck here, because
more and more often the networks rely on pooled coverage to save costs,
which means that everyone's airing the same cameras. Also, different
satellite and fibre transmissions have different delay times due to
different signal paths, so getting two different images in the same
"time" is quite unusual. In fact, I wonder if a slight delay between the
images might have yielded a bit of Pulfricht?

Film cameras recording history from slightly different angles relied on
crystal controllers for speed lock and will drift noticably...
