I have the vip211k Dish receiver with the OTA tuner. The unit works well, but several of our OTA channels do not show a guide. It just says "digital service". Some time back I purchased a little Ematic HD converter box. It is supposed to have a 7 day guide, but at most I get 12-24 hours. I have the thumb drive on the unit to record. Is there an HD converter box out there that has a 7 day guide? Better if it has a DVR. The local TV stations claim their guides go on for at least a week. Thanks.
