I am trying to set up ffdshow with Zoomplayer professional and would apreciate any input from CRT owners as to their preferred settings as I know that they will be different for digital projector owners. Right now I have older versions of Powerdvd and Windvd and Zoomplayer plays fine using either video filter without ffdshow. Once I check to use ffdshow neither one will work. With Powerdvd I get vertical green bars even though the movie continues to play and with Windvd selected the picture freezes immediately. I read that the windvd filters are preferred and that the abstract dmo needs to be changed to zero for windvd to work, but not sure how to do this?
