Can you receive hdtv signals on dig. cable?


Was wondering if you still need the externally mounted dish to get hdtv on digital cable. I have the round non-hdtv Dish network dish. Would seem simple to switch over to dig. cable and get a set top receiver to get hdtv signals. Don't want to buy another oval dish if i don't have to. Any recommendations?

hi It is possible for cable to do HD but they are using the digital technology to increase the number of channels rather than the quality of picture. $$$$$$ talks. I think at best digital cable`s picture quality equals that of regular satellite. I sell electronics and have heard complaints from customers who believed the cable hype about digital quality. And the price keeps going up.
