The default behavior of connecting KMP video transform filter is a bit changed to improve the playback performance with general systems. RGB force option including video processing effects and captures would not work with HD videos by default even when you selected High Quality option from Advanced Video Menu.
If you want to always use KMP video transform filter to force the video effects, switch back to the previous condition. Refer to the screenshot below.
By default, KMP video transform filter is disabled when playing DVD due to the same reason. You can enable it. Refer to the 2nd screenshot below.
