Having converted a good chunk of my CD collection to digital files that I can play it on a computer or my iPod, I struggled to figure out the best way to convert music that I own in DVD format (usually concert films). The solution is a handy piece of software called Audio Hijack Pro, available from rogueamoeba.com. This Mac software enables you to "hijack" audio output from any application on your computer (such as your DVD player) or via the computer's audio input. It also allows you to save any audio content played with streaming technology. And the recently released version 2.0 of Audio Hijack Pro allows you to save files in a number of formats (MP3, AAC, ALAC, or AIFF) and even imports them right into iTunes! A download well worth the $32 fee.
