When I first used Yade X to edit out commercials from a DVD the cut, copy, paste and most important delete options were functional. Now a few years later those functions are grayed out as well as the preferences for
Yade X. This occurs in both versions Yade X 1.0 and 0.99b. I know I can use MpegStreamclip but I remember how much easier it was to delete the commercials out in Yade X.
I have installed Yade X on an external drive to check for possible conflicts with other software and it still has no usable delete or preferences.
