The files are probably variable bit rate files. Did you copy them or did you transfer them with BP Trans.? Pamela Rader, TECHNICAL SUPPORT American Printing House For The Blind 1839 Frankfort Ave. Louisville, KY 40206 PHONE: 1-800-223-1839, Ext. 307 >>> wstephan@xxxxxxxxxxxxx 02/19/08 10:18PM >>> All: I recently downloaded an albem from amazon.com. Whenever I press the movement keys within songs on this albem, I get a "seek failed", error. Anybody know why this should be happening? Also, I loaded this onto a card using "my computer", if I use the BP transfer software, will it somehow mark the files so I can use the movement keys? Thanks in advance for any enlightenment.
