I have dish network, a Panasonic DVD surround sound system and a Vizio TV. I have the surround sound working with the TV now but I have to control the sound using a different remote than the one I control the dish with. Im trying to get my dish network remote to work with my DVD/Surround sound. I got on dish network's website and followed the directions using the codes they gave me and it still doesn't work. Im punching in the codes they gave me for a Panasonic DVD player. Should I be using another code from a different category? Do I have to continue using two different remote controls for my DVD/surround sound and my dish? Any suggestions? This is their website if that would at all help. Thank you!
