converting a lecture on cassette tape to an mp3 so I can burn a cd

Is anyone familiar with Ion Tape to PC USB Conversion System? I tried

using it to convert an 80- or 90-minute message from an audio cassette

to an mp3 on iTunes so I could burn it onto a CD from iTunes. I was hoping to have only one track (or at the most, two, because of the two sides of the cassette). However, the Conversion

System chopped the message up into 30 tracks that went into iTunes. I

would appreciate any suggestions.
