I have the HR24 DVR, and other people have told me that this problem is common. The problem is only with shows that are repeated later in the day , like on Fox News or MSNBC , or Comedy Central.
When you set up the Dish series recording, it specifies only one episode a day, DirecTV will tape unlimited repeats a day unless Tribune Media Services tells them not to. It is really a hassle to be constantly cancelling and deleting all of the recordings.
There's a work-around that you can do to record the time slot manually, but that is more time-consuming and also it won't delete the old episodes automatically.
Does anyone else have the HR24 and seeing these repeated episodes?
