Audio won't play

Hello,

I've been experiencing some trouble with getting audio to export when I build a
dvd. In edition to that, when I do get the dvd to burn with audio the audio
plays on my dvd player, but not on my friends dvd player. Any suggestions?

Is the audio MPEG-1 Layer II? MPEG audio is only an optional format - a set top
player may support MPEG audio, but isn't required to.

      I haven't used MPEG-1 as any means to burn/transcode/export my project.
      I've only recently had this problem. I use to burn projects that worked
      in both our players without fail. How do I get my audio to be Dolby
Digital
      (AC3)?




How is your friends player connected up?

I'm not sure how his player is connected, but I'll ask. What I find unusual is
how he and I have been testing footage on both our players for a year and
suddenly his player is having trouble with recognizing/playing audio.

I'll check the Edit/Preferences/Audio & Video
