if the regular cable connectors are red, blue, and green in color, you have a hd picture. if it's one yellow or one coax cable, you're right, you could be paying for hd you're not using.
or, you could be using the hd box in sd mode. you might want to have geek squad or another local indie av tech come by and help you out. there are still options to get both in hd, if you aren't already.
