TV Tuner card not reading from Composite

This is a different problem than the other thread going on here..

I have a Winfast TV2000 XP tv/FM card. Now it can display from the Coaxial input just fine, but when i try using the CVBS connection (composite) it wont show though. Im using the WinFast PVR2 Software, and its on CVBS mode, the Sound will come though, but not the video.. I got the latest PVR 2 software and the latest drivers off Ledteks website

Any ideas why this wont work? (im trying to hook up a game console though it, ps2/Wii)
