Live TV Help in Media Center

I have installed a Wintv-hvr 2250 capture card

Operating system Windows 7 pro 64 bit

I have set up my satallite reciever and I am using Windows media center , the problem is live TV will not play in full screen , all I get is Letter box type setting , and I can not find a way to get full screen in live TV mode .

Movies show in full screen , and if I run WINtv7 it plays live tv in full screen , but not in Windows Media Center ,
ANy ideas how to get full screnn mode in Live TV in Windows media center
