The patching is usually just removing the media-check from the game so I imagine it'll work fine.
They will be fine if burn on a single DVD.
However I've found issues with some games and menux when creating a multi game dvd. Some games fail to load from menux, this could be they are PAL games and switching between menux ntsc -> pal causes some issue?
