My local PBS ran a HDTV channel at 13mbs and a 480p channel over the weekend to try to have HDTV for us that want HDTV and multicasting for the station general manager way of thinking. No sound during the tryout and alot of pixels on 13mbs HDTV. I called the station today and was told that another Dish 6000 owner has called on the problem. The station has gone back to 480p channels but still no sound on my Dish 6000. The other digital stations sounds come in loud and clear on my Dish 6000. I removed the station from the program guide and reloaded the station but still to no avail. I even tried a different 8-VSB module and I still have no sound on this digital channel. Any ideas?
