This works well because you can not only convert CDs, etc., to mp3 format, but old cassettes or records. You use a simple cord to connect the cass. deck or turntable (1/8" cord going to computer, "RCA plugs" at other end). For CDs, you can use an external CD deck with the same adapter, or go right from the CD-ROM of your computer.
...meaning _plug_ that goes into comp. is 1/8"...same size
plug as used in "Walkman headphones"
You wasted your money, IMO.
Easy CD-DA Extractor and iTunes do excellent jobs for $0.
