Thinking of cancelling dish

wondering if someone can help me out. I have just upgraded to HD package less than a couple of days ago. I am really not impressed with the new channels and the extra sat. dish outside my house. Do you guys know if I can cancel the dish HD package and just go back to regular TV? would I have inccur any charges for this ? Any help would be greatly appreciated...

Dish is really the one you should be asking. But if I recall, you have a 30 day guarentee
