Restoring PC Backup Files onto New Mac

After my desktop PC crashed, I decided to go with a Mac.  How to I convert my backup files on DVD into a usable format?  My PC laptop with the same Norton 360 program doesn't recognize the files, nor does the Norton Program itself.  Any suggestions?

 

Thanks 

Since the desktop PC is toast, my best guess is the laptop software, which is 2.5.0.5

 

I don't want to reinstall the entire computer profile, just be able to access the individual files. 

And I was able to see the files on the laptop a few a month or so ago, perhaps the software has been updated slightly since the backup.  The files are form 11/15/08.
