I'm going through the pre-long-flight iPod prep ritual. Last time around I had trouble hearing a bunch of movies I'd loaded (that were all about the dialogue) over the white noise of the airplane environment, even turning the volume (and max volume limitation) all the way up. I want to try to avoid the same frustration this time around. I'm ripping a bunch of DVD's using Handbrake, and I'm going to try setting the DRC to 2.0. (This is my first time using Handbrake; it's actually for my dad, who usually takes a DVD player but just got his first iPod.) Should that be enough? And what about files that are already ripped & compressed? I recorded a couple of movies with my EyeTV, and I want to make sure they're loud enough. Is there anyway in QuickTime to increase the volume & re-save? I'm not looking for stellar audiophile-certified sound here; just the volume & passable clarity to get me and my parents thru a 9-hour flight. Any and all advice is welcomed.
