Create AAC Version?
In iTunes 8 on my iMac, I noticed that items I recorded myself had the contextual menu option "Create AAC Version." In the older version of iTunes on my eMac, the menu option was "Convert Selection to MP3." I actually prefer the AAC version because of its smaller file size, so I lugged my eMac into the other room, connected it to the Internet, and updated iTunes to version 8. But when I looked in iTunes on my eMac, it STILL only gave the option to convert to MP3! Why the difference between the two Macs? Is it because of the different processors?
