I saw no rules about questions like these, nor could i find the answer on google..

I wanna burn FF7 on dvd for PERSONAL use, NOT profit.(would you wanna watch the bahamut or sephiroth/cloud battle on a 65" tv?)

I sent the file to my friend and he burned it the way he normally would for his music videos he plays in his car. Only problem was, he got no sound. He played the file on his computer nad had no sound. I had him install the codec for AC3 audio and it worked. So he burned another copy and STILL no sound. He uses Nero 6 i belive. What else is he doing wrong? his other videos burned well with sound no problem. Also whats the best settings he should use for video? i tried the dvd on my dvd player, still got no sound, but it was looking all pixelated.. Can someone help?
