Has anyone experienced choppy sound problems encoding recently purchased CDs? I have been using iTunes to do my encoding on the Mac and it has been working fine, but recently I have been getting slightly rough sounding rips with a choppy quality to them. Is this perhaps due to some copy protection scheme incorporated into modern CDs? If I rip the audio off the questionable CDs using Astarte CD Copy for the Mac, and then encode with iTunes, the choppiness is gone. I have so far only experienced this with the Creed Weathered CD and the Men at Work Contraband CD, both of which I purchased within the last month or so.
