In theory this shouldn't happen, but we all know it does. The TV companies should transmit signals telling your recorder when to start/stop. Unfortunately some of the companies are much worse at doing this correctly than others.
This is a reply from Freeview to a similar complaint:-
Dear ,
Thank you for contacting Freeview.
It is the individual broadcaster that is responsible for sending these start/stop signals out. BBC are usually very accurate and often other broadcasters less so, but this is evolving technology and hopefully it will improve dramatically across the board in future.
If we can be of any further assistance please do not hesitate to contact us by either calling us directly on 08708 809 980 seven days a week from 8.00am to 10.00pm, or again by email to
