Don't actually go to the channel do it in the channel list without opening them. Go to each on the list, press yellow button, enter password, go to next etc etc till done. Then exit to main menu and go back into live TV they should all be open. If you missed any just do them and repeat, they should stay unlocked as long as you don't factory reset, uninstall TVOnline (on VIXO1) or they change the main channel list.
