I'm trying to copy my iTunes library to a thumb-drive so that I can play it in my car ( it has a USB plug). My problem is that the car can't play apple
Lossless, which is how I've ripped all the music in iTunes. For one of my iPods, this is very easy, where you can choose to down-res your library during the sync. Is there a way to do this using the export function? Should I just copy the files and move them to the thumb-drive and then down-res them? If I did that, how would I keep iTunes from down-resign my original library. Advice please!
