Jeremiah: Book Port has always reversed the channels of stereo MP3 files. This is = not a problem with the beta firmware; this is a hardware problem. The best = thing to do if this bothers you is to use a set of headphones (or ear = buds) that is reversable. That way, you can get proper channel orientation = by wearing the headphones backwards.

I've noticed, with the combination of the beta test =3D seven firmware and the last three betas of the software, that the Book =3D Port is reversing the channels of stereo files played with it. I've yet = =3D to determine whether the glitch occurs when transferring files through =3D the transfer tool only, or if it occurs whenever the device plays stereo = =3D files, but I have most definitely seen the switch. The track I've tested = =3D with, in case anyone has the CD and wants to check my results against =3D their own, is Journey's "Don't Stop Believin'" from the Live CD. The =3D piano should start on the left, with the guitar on the right, but on the = =3D BP this appears opposite of that. I'll be happy to provide the MP3 to =3D APH, and only APH, for their testing if requested. I sent this file to =3D the device via the transfer tool, though the files which made me work to = =3D investigate the potential of the behavior were sent to the Book Port via = =3D simply copying them to the flash card itself. Thanks in advance for any = =3D responses which come forth. Jeremiah
