Hi -
The program you want is Radio Wizard:
http://www.applian.com/radio-wizard/index.php
This one is an ideal listening companion for radio. As you listen, if you hear a song you want to record, you can "rewind", then record it.
It'll do just what you want to do, and work better than the other program you are using.
Best Regards,
