This is affecting me at the moment. I watch cycling and the Criterium de Dauphine is currently on 
(UK) ITV4. So far, so good, but it follows the Roland Garros Tennis, which almost always over-runs. 
Sometimes it is an hour late and I've had to put 65 minutes post-roll.

In that situation I have no idea how RK's commercial marking data would cope.

I believe that this is a general problem with sport programs, especially in the US, but it can be 
experienced around the world. Apart from adding an automatic hour post-roll to every sports program 
I have no answer.

I have always added 5 minutes pre-roll to all my schedules. Most programs start near enough that 
there is no problem, but one or two channels seem to 'jump the gun' too often. Now that playback 
jumps to the start of the program, not the start of the file, it is easy enough to go back a few 
seconds if it began early.
