<DIV><FONT face=Arial size=2>Hi all,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I got the reason by myself ----- The <FONT
face="Times New Roman" size=3>vtkWin32VideoSource are written in VFW (Video For
Windows). And <SPAN style="FONT-FAMILY: Arial"><STRONG> Pinnale
510</STRONG></SPAN> usb does not support VFW as most camera does. Now my
problem is how to find a usb video capture which support VFW---- all of them do
not mention this issue in their Spec.</FONT></FONT></DIV>
