Hey guys, I have a Magnavox MDR-513H/F7 Digital Video Recorder. The audio on two channels has stopped working. A couple days ago, one (maybe both) started playing SAP audio, where it says extra stuff about the program (e.g. "John walks into the room and sits down"). I thought it was kinda funny, but then audio (both stereo and SAP) stopped working on these 2 channels. :/ I have rescanned channels multiple times, and also did a manual scan on these two. The two channels work fine on another system, so it's not a broadcast problem. We get 7 channels (10.1, 10.2, 10.3, 12.1, 12.2, 12.3, 12.4 ). 12.2 and 12.3 are the ones with no audio, but 12.1 and 12.4 work just fine. Any ideas? Thanks.
