I've not had this issue myself, but only because I don't record a lot.
However, many users do come across it quite often, and it must be really annoying.
My understanding of the issue is this...
The program maker or broadcaster provide metadata to people like Youview/BT, for example, when I program is due to start and end, and the Youview/BT box then uses this to control a recording.
The problem is that this metadata often doesn't get updated when I program runs late, (it should be!), so the box cuts of the last few seconds or minutes of the program.
There is however there is a very simple method for handling this, which many boxes already use, and that is providing a setting that allows users to select a "padding duration" to a recording, for example, 1min, 5mins, etc...
So even though the box receives the metadata from the broadcaster that the show should have finished, the box adds on the amount of time the user has selected, which on most occasions is enough to manage the overrun.
However, for some reason Youview/BT seem unwilling to implement this common feature, and I'm not sure why.
I can only guess that there may be some complex legal reason, however, it is a common feature on boxes and a simple solution to the issue.
I can only suggest that we come together and try and rise support for the feature through these forums, that way BT might start to take notice, or, explain the reason why even if they wanted to implement it, they can't.
