RE: [Deinterlace-discuss] Modify DScaler

[Deyan A. <di...@ku...>]

Hi,

I had similar problems. Once you've set the WDM driver as a source for
DScaler, set the source as default (from the same menu "Define as initial
source"). Then exit DScaler and restart. When you run again DScaler it won't
initialize the internal driver but the WDM driver so the DirectShow source
should work as expected.

Regards,
Deyan Atanasov
