We only support WDM drivers, and I have personally tested the iTuner
Spectra8 as well as the Winnov Videum.

Natalia:

As far as I remember, the iTuner Spectra card already uses wdm drivers,
so it is less well 
supported than the winnov card for multiple capture in windows, thereby
further making the 
case for wdm support in vic.
