I've been using a Hughes GCEBO DTV Receiver for the past few months. Although all of the current DTV channels use a three numeral channel designation, this receiver was programmed to use four digits. Thus I could start my dialing with a zero followed by the three digits, dial three digits and wait a few seconds for the receiver to switch channels, or dial the three digits and hit "Select" to change the channel. No big deal, not hard to do. But, yesterday, I noticed that the receiver is now programmed in the more conventional three digit format and there is no longer any need for a fourth digit. Is this something that DirecTV automatically transmitted to my receiver? Also, does anyone happen to know the reason for this change. I'm just curious about the change. It, obviously, has no real effect on my receiver usage. Thanks.......
