Today, all of the phantom recordings reappeared! Yesterday, I was able to delete the recordings. When they were deleted, the recordings disappeared from the list as you would expect, and I thought that the problem was solved. However, today when I logged in to Dish Anywhere, all of the recordings reappeared in the list of my recordings.
When I delete the recordings, they seem to be deleted, but if I close the Dish Anywhere window and reopen it, all of the recordings reappear in the list. In all, there are 14 different titles, and a total of 33 recordings that seem to be left over from the previous user of my refurbished receiver. I cannot play them and I cannot delete them.
