Why is my Sylvania HDTV w/dvd player showing a blurry picture? - hdtv dvd player excellent first generation high definition dvd player

I bought my first HDTV flat screen. It has an integrated DVD player. Shows the DVD as I thought, was a show of HDTV. But that's all. When viewing regular TV, I get a blurred image. I am new to flat panel displays. Do I need something to make the image clearer. Oh, I regularly DirecTV definition is not very high.
