Hi everyone,
Please help me

I installed my copy of Vista and set up Media Center.
After it I bought a TV tuner card ("Pinnacle PCTV 110i Capture Device") and
with about 20-25min work I managed to install it's driver. After it Media
Center successfully recognized the tuner card so I tried to search for
analog services. It found about 55 so I went to the live TV feature. The
problem now comes

I hear the voice of the TV service, but I see a black
blank screen instead of the picture (and after a short time it shows me an
error with title: "loss of singal"), but in Windows Live Messenger I can see
perfectly my TV tuner's picture as a webcam. I tried to use the Live TV
function after killing msnmsgr.exe but it still doesn't show a picture. I
attached a print screen about the problem. Please help me if you have any
ideas what should I do.
Here is the link for the print screen:
