I recently replaced an original Hopper with the new Hopper w/Sling. Before replacing my original Hopper, I download about 139 hours worth of recordings to an EHD which I have used for the past year successfully with the Hopper. After the install of the new Hopper w/Sling, I transferred most of the recordings back to the new Hopper. On transfer, the hours on the new Hopper w/Sling showed the recordings to amount for the same amount of disk space as previous. The shows were all listed as well as correct dates of original air time. I did notice they all had a record date of 2/07/2006. When transferred, they all showed the same thumbnail blue slide. Overnight the actual picture icon for the show populated. Here comes the problem. When I now choose to view any of these older programs, I get a message on screen that says "Event playback finished. Press the Play key to start from the beginning." On doing this nothing happens and the screen goes black. If I pull up Info on the show, all the descriptions, air time, are correct New shows are being recorded and playing back properly. Old shows I had left on the EHD continue to play fine. Transferring one of these shows back from the new Hopper w/Sling to the EHD still leaves the show unable to play. I have rebooted the new Hopper w/Sling and nothing changes. I call Advanced Broadband support and they acknowledged they are aware of a software problem on recordings transferred back to the Hopper w/Sling and that it is currently being investigated. They suggested that I keep the "not working" recordings on the unit in the event the SW is updated and renders them useful again. In the meantime, I recommend that anyone upgrading to the new Hopper w/Sling that is transferring recordings to an EHD with the idea of transferring them back to the new Hopper, just leave them on the EHD until they solve this problem.
