Coding problems perhaps? HELP

[suefyzah]

I wish to capture some live video and preview, but PlayVideoCap example that i downloaded from Windows SDK, (DirectX) just doesn't do the job. It compiles and there is no error messages. video preview show black screen,although avi frame capturing works fine.. and video capture with VideoCap works. I wish to capture from the Capture Card as well and currently using a surveillance camera.

I am beginner in video programming C++. What possibilities of mistakes there may be? Any advice please! Any other sample codes??
Thanks in advance.

Cheers,
kel

any help is greatly appreciated.
