Hello, I have been recently attempting to transfer some of my music stored in iTunes to my USB dongle based MP3 player as well as my Sony Ericsson K750i Mobile phone. Upon finding the albums I want to transfer over, I just drag and drop the folder itself to the specified area(in this particular case my mp3 player) and it begins transferring the mp3 files which were made using the iTunes ripping program built in. Oh lovely I thought, until after spending about nearly an hour transferring over quite a few albums I found out that it has somehow been duplicating each song twice-one is playable(1st) the other is not(2nd). This meant that out of 2GB available, half was totally unplayable!!!! This is what I seem to get: 01- Message In A Bottle.mp3(this one plays) .-01 Message In A Bottle.mp3(this one will not play at all and it's always named after the one above which plays, it just says invalid format. I have tried another mp3 player and the same thing happens, so then I tried using a different mp3 ripping program(Audion 3) and that seems to do the same thing as well, does the .- mean anything? Michael.
