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.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.
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.
