Hi Guys & Girls, I am using WinMCE with nVidia DVD decoder and nVidia 6600 graphics. Deinterlace control is set to "Smart" and method to "Best". I have noticed several DVD extras and menus are not deinterlaced correctly unless I set deinterlace control to "Video". My question is what would be the down side of leaving this set to "Video" and hence forcing deinterlacing on all content including progresive film? I realise film doesn't require deinterlacing but will I loose picture quality by doing this? Any thoughts greatfully received.
