We use DISH Network at home. They have a good package and it comes with DVR. Unfortunately, I've had some issues over the last couple of months where movies that we recorded and planned to keep relatively forever (or until I own a DVD-Burner) just disappeared from our list. These were movies that the whole family loved like Harry Potter and the Goblet of Fire, the SpongeBob SquarePants Movie and many others. I went to play them one day for the kids and they simply weren't there. Many of these had been Pay-Per-View films that I felt like we'd bought, even though we'd only really rented them.
A few calls to DISH Network's technical support team didn't get me very far at first, but eventually the tech and I decided that it must have been a power surge or something that had caused a problem with the hard drive in the machine and that the box itself would need to be replaced or the issue would continue to happen. It seemed unlikely to me, but I was ready to try it. The problem of course is that there is a backup of other films and television episodes that will not transfer from the old box to the new one. So I have to either watch them all and delete them or just let them go and put in the new box.
Just another minor dilemma brought about by technology.
