no sound on dvd player - newbie question

[danped]

Hi,

I might be doing something really stupid here but here goes...

I've got two folders for my DVD one called VIDEO_TS with some VOB, IFO and BUP files and I've got another folder AUDIO_TS which is empty. I've burned these folders onto my dvd using nero. However If I put the dvd into my player it plays without sound, I know the sound is somewhere though because if I play it on power dvd it has sound! How should I burn it to have sound on my normal player?

Thanks,
