If a channel is recorded using "VPS" (which is implemented by using the
PDC descriptors), a particular event has its official broadcast time
encoded in the PDC descriptor, and that's how VDR assigns an event to
the timer. Whatever that event's data is at the time the recording starts
(which happens when the "running status" of the event goes to 2) will be
stored as the recording's info.
I don't see how "waiting a few minutes" would do any good here.
