Club menus look ahead to midnight and count repeat broadcasts

A three-hour window was empty most of the day, which is exactly when
someone wants to know whether their club plays tonight. The scan now runs
until midnight, never less than three hours, so a late-evening question
still covers the rest of the night.

A channel can carry several of the club's broadcasts in one evening — a
preview at 18:20 and the match at 21:45 on the same station. The row names
the next one and appends "+n weitere" instead of silently hiding the rest,
so the list stays a channel list where one click means one station.
