I have tried to burn several widescreen movies to .iso files, but some still register as 4:3 format when they are ripped. This causes a video that does not fill the whole frame. Widescreen movies that show up as NTSC 16:9 rip as widescreen format with letterbox black above and below the video. If it is a widescreen movie that shows up as NTSC 4:3 in clonedvd than I get black bars on the sides and above and below the video. Is there any way to fix this?
