Hey guys, I'm going to be traveling a good deal soon and I'm in the process of ripping a bunch of my DVD's into my iTunes so I can watch them on my iPad. So while ripping with handbrake I noticed if I leave out the AC3 passthru track I can save roughly 300MB per movie, which is great so I can cram more movies on my iPad. My questions is, what do I lose by cutting that AC3 passthru? I believe all that is for is if I was playing the ripped movie on my Apple TV or something with 6.1 sound, right? Am I correct in thinking I won't notice any difference without the AC3 passthru track when watching on my iPad or with iTunes on my computer? The iPad and iTunes only utilize the ACC (CoreAudio), right?
