Can anyone help me... Somehow BBC 2 has locked on my matsui box. On the channel list (menu) it has a smiley face denoting the fact that its locked, but I didn't lock it. Maybe I did it by mistake?! Anyway, to unlock it you need a code...and I aint got one. The consequence of this is that I can change channel if I punch it in numerically, but not if I press P+ or P-. Any suggestions out there? Many thanks.
