I'm making program to show Live Video in Picture Box directly from small camera plugged in 'S-Video In' port on Graphic Card.
I know how to open and play AVI files by using mciSendString API(code example):

Sub PlayVideo()
Dim returnstring As String
Dim erg
returnstring = Space(127)

erg = mciSendString("open " & Chr$(34) & FileName & Chr$(34) & " type AviVideo alias myvideo", returnstring, 127, 0)

erg = mciSendString("window myvideo handle " & Picture1.hWnd, returnstring, 127, 0)

erg = mciSendString("play myvideo", returnstring, 127, 0)

End Sub

That's it... But how to initialize and play, Video which is not saved ? I need help to show that Live Video in Picture Box. When I say Live Video I mean that small camera(WebCam) directly and constanly shows video. With my graphic card (NVidiaRiva TNT 2 Ultra) comes software 'Asus Live' which can directly plays video in window (from WebCam trough S-Video In port on the card). That is what I need, but I have to make easier program with some options what 'Asus Live' can't do. I only want to know how 'Asus Live' display Live video in Picture Box or Form (I think with few calls of mciSendString API, but my work wasn't successfull).

Any help is greatly appreciated.
