Please see http://www.avforums.com/forums/showthread.php?t=232209 for a pleasing update on this thread! Ladies and gentlemen, I have news. My friend has taken some tracks (DRM-free using SonicStage version 3.2) created on my PC, and tried to load them onto his HD1. The results, I'm afraid, are NOT what we all hoped for. Basically, file-swapping is still a NO NO! Looks like the DRM-free business might merely help the individual when, say, swapping a PC hard drive or restoring after a serious system crash. Other than that, no swapping seems possible (at least, not with ATRAC3Plus files). Anyone know any different?
