Try doing a seach in the Club Rotel forum at
[Link: htguide.com]. We've seen similar issues with various cable box's before but not any that I recall that require a reboot of the 1068. I do know that many cable box's seem to have problems with sending out a digital signal all the time even when not required which can trick the Rotels into trying to lock onto the low level digital signal...if that's the case short of replacing the cable box your only solution is to switch to analog cables
