I have a Power mac G4-mirror front, Duel 1.27 MHz running OS X 10.3.9, with 768 mbs of RAM. The basics, but enough to run iLIFE, right? After completing my podcast and hitting export to either iTUNES or iWEB, Garageband runs me through all the normal stuff, converting and such, but never gets me any further. Has anyone experienced any problems similar to this, and can anyone help me?
