Lenco L-3866USB to Mac OSX, 10.7.3

Can you help me with information how to install my: Lenco L-3866UCB to my Mac OSX, version 10.7.3? The disc I got some years ago with my Lenco machine doesn’t work on my new Mac. Are there new install-discs? Or do you have a program I can download and is there a description and initial starting up with such a download?
Hope you can help me, I want to play my old discs on my Mac, put them in my Itunes and make discs.
Thanks for your help,
Aukje Holtrop
