OK I need to know what is everyone's thoughts on the audio?

I will say this,if I upgrade the audio for ANH,then there has to be upgrades for the other 2 as well.

I would like to add the 5.1 audio I just got from satanika if it does not go over in size,as a bonus audio option.

and this Belbecous audio file everyone keeps talking about,is there versions for ALL 3 movies?

So please give me your thoughts on this issue.

I was just originally going to do the video and leave EVERYTHING else on the retail DVD untouched.
