Ive had the 3410a since May. I have the 1.12 firmware. It has worked flawlessly until 3 weeks ago. I am using it for OTA HD recording only. I can still set the timer manually, and the shows record and playback fine, but the guide has had 2 problems. 1st it was assigning the uhf numbers to the data 34-1 , 48-1 etc. I read another post on this subject and edited the channels to 4-1 9-1 etc. This corrected the problem and I was able to use the guide for about a week. The last 2 weeks I have had no data at all in the Guide. I live in the WASH DC area and wonder if others are having the same problem , or if so have a solution. I have rebooted the system pin and no pin , unplugged for several hours , still have no data in the guide. Any one have have a solution for this. The unit works fine otherwise.
