I bought one of those devices quite a while back but could not get it to work with GStar capture or PHD. I concluded that the driver only works with applications that support DirextX9 DirectShow like VirtualDub. The other apps require driver support for WDM/VFW
Gave up and bought one of these, worked perfectly straight out of the box except for the annoying bright blue LED.
