Dave: Yes, you will have to change the extensions to send the MP3 files to the = Book Port. I hope you can figure out why this is happening.

Something seems to change the mp3 extension on these file names to mpga. So am I going to have to rename the files after downloading? I want to eventually transfer them to the = Bookport. That is why I believe this message is on topic for this list. Cheers, Dave
