I tried ripping my Cloverfield DVD with the "5.1 English" audio track and there was no surround sound when I played in on ATV. When I tried the "5.1 English Surround Sound" audio track, there was surround sound, but it had audio commentary. I tagged both files using MetaX. When I play the DVD in my Blu-Ray player there is surround sound. Is there any solution to my problem? Thanks.
