Yes an automatic scan will pick up channels you are missing and they can be found at the end of your channel listing
That was a long scan 2 days What provider are you on and what channels are you missing, I presume you are scanning directly from the incoming feed?
provider? the channel that was deleted is bbc1,just went into the menu and scanned from there. just got the box so forgive the fact that i havnt got a clue. oh and its my sisters box so im trying to do it without her knowing i deleted a channel,ha ha.
