The Symphony III will also now play MP3 CDs whilst I'm not sure the external changer will so that's another advantage. I know you said you're not into MP3s but with a PC, CD burner and some free software you can easily cram 10 times the number of tracks onto each disc so it's worth looking into.
Whilst I am fully computer literate, having spent some 15 years supporting a computer network starting back in the days of MS-DOS I have never really looked into the question of using MP3 files. I current just copy my CDs for use in the CD player in the car.
I have a computer with a DVD-ROM and a DVD recorder drive. What software would I need and basically how does it work. Thanks.
