Does anyone else get the 'Content Error' message while watching the BBC Iplayer on a Sony Bravia with a Sky Connect broadband connection?

Quite often the program simply stops with 'Content Error' and I think I know know why!

While doing some web design, I leave the connection to our database open, but when I return after a couple of hours, I need to reconnect to the database, because it reports that my IP address has changed. So I'm assuming if your IP address changes while watching a program, the connection fails!

Anyone know if this could be an issue?
