Audio preview for DVDs

Hi all,

This question isn’t exactly specific to aTV Flash, more of an AppleTV question but I thought I’d try it anyway.  You know how, if you have a DVD folder you want to play, you can save a JPG of the poster frame alongside the VIDEO_TS folder (as “preview.jpg”) and when browsing your movies it will display your poster frame in the main menu?  Well, I am curious if anyone has ever figured out if it’s possible to also have it play a small audio clip at the same time?  Like maybe saving a “preview.ac3” alongside the other “preview.jpg” or something?  I’d test it myself but I don’t yet have an AppleTV (waiting for Christmas) and was curious if this is even possible, and how to do it.  It would be sweet, wouldn’t you agree?
