I have a 2 gig bluray rip mp4 file that plays great with audio on my laptop. I tried to use nero vision in nero 7 to convert to a dvd playble in my home player. It expanded to a file size that filled up my dvd and it plays great on all of my home dvd players...but i have no audio. Weird, because I have audio when i play the mp4 file on my laptop. Does anybody know what i can use to convert the mp4 file to a dvd that will play on my home dvd player?
