IMHO you can just set composition option to PAL@25, and re-render menus to PAL
Video….you have 23.976+pulldown or native 29.97fps ?
If you have 23.976fps videos, you can speed-up your video and audio without “Lightening Media in Los Angeles”…I know how to do this “hack” on PC/Windows – try to use Canopus ProCoder or Carbon Coder.
Audio – any audio editor, you must to apply “time stretch” filter and speed up to 25 fps (multiply speed to 1.042709)
