Hi Becca: You need to use iTunes to convert the tracks to AAC. Select the tracks and choose "Convert to AAC" under the "Advanced" menu. This will not destroy your mp3 files it will create new mp4a files. Once this is done fine the files that were converted and change the mp4a to mp4b. This will make the files bookmarkable. For any Mac subscribers there is an apple script that does this automatically, but with the PC I think you need to change mp4a to mp4b manually http://dougscripts.com/itunes/scripts/ss.php?sp=makebookmarkable Ken On Feb 21, 2009, at 9:43 AM, Becca wrote: > > Just got a new book (Promises in Death - Yea!) from > audiobookstand.com, in mp3 format.
