I've downloaded ffdshow to use with tweaking the image of DVDs that I watch on my computer but I can't seem to get it to work. That is, every thing I configure has no effect on the image of the DVDs I play in WinDVD. Am I doing something wrong or will ffdshow not work in this case? I mainly want to set sharpness and zoom in on non-anamorphic DVDs. I've tried selecting all codecs but with no luck. any help would be appreciated.
