Last night at 3:00 AM, my cable box rebooting for a mandadory software update. When it csne back on, every time I pressed a "0" for a channel, such as for ESPN HD at "570" the channel was entered as consecutive "00s." In the example given, it was "5700" and that obviously is not a valid channel. I tried multiple remotes, but the problem persisted. As you can imagine, this is REALLY annoying!
