Any idea on how to avoid this?”
It's how it's supposed to be, the picture is transmitted intended for slight overscan - try looking at the BBC testcard when it's on the BBC HD Preview.
Some sets have a customer setting allowing direct pixel mapping, if your's doesn't then you can't do anything about it - but to be honest, it causes more complaints than not having it switched ON.
