Okay, the book that gave me the problem (absolutely no navigation whatever) shows as a bit rate of 128kbps, sample rate of 22 kHz. Should this have worked as advertised or not? I don't remember if I used the Send As Music choice, but according to the manual, whether I did or not, I should have had functionality from the 3, 6, and 9 keys and I didn't. -----Original Message----- From: bookport-bounce@xxxxxxxxxxxxx [mailto:bookport-bounce@xxxxxxxxxxxxx] On Behalf Of Walt Smith Sent: Friday, July 06, 2007 6:46 PM To: bookport@xxxxxxxxxxxxx Subject: [bookport] Re: Seek failed error when playing mp3s That's the other shoe and perhaps the answer I was looking for in my earlier message. I'll have to check the file to see if it's VBR or not.
