I have a VIP 722 with Dish Network subscription and I also have a Panasonic DVD recorder. I have recorded a few shows on the Dish DVR hard drive that I'd like to save on a DVD (ram, r, r dl, rw etc) and I connected the DVR to the DVD recorder. I get the image recorded on the disc but no sound. I tried every cable connection possible, RCA, S video, nothing seems to work. Any ideas?
