When I run a search on Limewire, 99% of the time the file type that shows up is "MPEG-1 Audio Layer 3". When I double-click files of this type, I can hear them on the Limewire Player, but they are not automatically transferred over to my ITunes library. If however, the file is of the type, "MPEG 4 Audio", when I double-click it the file will play and is automatically tranferred over to ITunes (and can then be subsequently put onto my IPod).

How do you "instruct" Limewire to always download files as MPEG 4 Audio? I have used Limewire at friends houses, run the same searches, and the same files end up in their libraries as this file type.

Thanks!
