We have had recording "anomalies" ever since we got our Hopper/Joey.
We will set up a recording for something, check it in the morning and confirm that the recording is scheduled, come home that night and find that the recording did not record and the scheduled item doesn't even show in the history when we try to check to see why it didn't record. This happens most often for football games but sometimes with other "one-off" programs as well.
The flip-side is that we will see that a recording for "Sports Center" or "Sports Today" has been scheduled for 6 in the morning or 11 at night. This seems to happen when other recordings have disappeared.
I thought maybe someone else in our neighborhood had the same remote frequency but our nearest neighbor is an acre away and has DirecTv. Plus, if that was the case, I think we would see this happen more often than we are seeing it. We didn't have this problem when we had our 622.
Anyone else experiencing this type of situation?
