I understand that you are frustrated, but your last sentence is a little
offensive.

The OpenGL vsync/bobdeint combo is awsome.  Ever since Doug implemented that
combination, my video playback has been silky smooth.  I have an nVidia
graphics card.

The reason it may not work as well for non-nVidia users, is that Doug uses
an nVidia card.  Pretty much all the "developers" use an nVidia card.  This
means that all other video cards are not going to be as well tested or
optimized.

If someone wanted to buy Doug an Asus Pundit, he *might* be willing to take
the time to work on improving bobdeint for non nVidia cards, but he is
unlikely to buy one for himself just for that purpose.

Doug would probably be willing to explain how the bobdeint code works, if
someone without nVidia hardware wanted to work with it.
