I created playlists from the library of iTunes then loaded the lists on the iPT. Many of the songs would not "play", that is the time indicator moved but there was no sound. I checked the properties and they are "protected AAC" files vs "purchased AAC" or MPEG which both play OK. What can be done to correct this. This is new iPT with 2.0.2 update as of last week. Songs which I have copied to iTunes from my CD's play OK and the iTunes is set to import CD's with "MP3 Encoder". Is there a similar setting for acquiring songs from Apple into iTunes. What can be done with the songs already downloaded from iTunes that are "protected" so that I can play them on the iPT?
