I have an HR24 DVR. I record 3 episodes of an old tv game show early every morning and watch them over breakfast. This morning two of the episodes recorded twice. The episode at 6 am recorded twice (same time same channel) and the 6:30 am episode also recorded twice. 7 am recorded just once. To be clear, the duplicate show was same time, same channel, and it recorded twice. Didn't even know a DVR could do that. Any thoughts.
