On occasion my DST-3000 downloads what appears to be a partial listing of the channels available on DTV. All channels are listed but the show title is listed as "to be announced". I've tried dozens of things to get the guide to update, but the only way I've found to get it to update correctly is to remove power from the unit. Anyone else experienced this type of situation? I've got 2 other RCA receivers that do not exhibit this problem.
