• Just select the channel and press the ENTER(OK) middle button on your remote control and say Yes.
• As rooobb said you can permanently delete those channels at Digital (DVB-T).
• But, you cannot do that for Satellite channels. Even if you delete them, even if you disable automatic DVB-S channel update, those deleted, inappropriate channels, COME BACK, re-appear themselves automatically and re-arrange themselves automatically.
• Sony is informed but have done nothing yet for more than six months.
