I've been under the assumption that since H264 is the core of Blu-Ray, if I convert video to H264 with a mp4 container, these files will be able to play on a Blu-Ray player yet. But since I don't own one yet, I'm not sure just if I'm wasting my time. With DIVX/XVID avi files I just get a list of files on my DIVX capable DVD players. There's no need to create a menu. Will H264/mp4 files appear the same way in all Blu-Ray players? Or will I have to create a Blu-Ray compatible menu and convert all these files again? Thanks!
