I would like to see the option to make left,right,top,bottom offsets for TV's that display portions of the screen to far past the edge of the screen. For example go to the video settings is OpenBOR or the settings in PMPlayer Advanced. It allows to offset them in 00.00.00.00 format. This could get rid of all the different full screen modes and allow the user to customize the screen between the 420x272 centered screen like the standard Sony PSP to full screen that does not need to be cropped.
This would also allow for conformed coding of filters and such as listed and also would allow uniform coding. From reading other posts and personal experience certain games perform better in different full screen modes.
By the way, LOVE THE PROGRAM! Keep the good times rolling! (now that I have full screen)!
