ok its hard to see what you want to do from your post..
i am guessing you have original CDG discs and you want to play the tracks on software you have on your laptop.
if thats what you want to do then that depends on the software you have
for example if you owned MTU's hoster then it has the ability to play CDG directly (no ripping) it has a ripper built in and a data base to label all the ripped tracks correctly it changes the file format from the raw bin file on the disc to its own dedicated file format (KMA)
if you had PCDJ , swift elite virtual dj etc they like karaoke files in the MP3+G format now to do this you need to rip the files from the discs with a tool such as ;
MP3+GTOOLZnow some software will take the MP3+G and then convert it to a format it likes better i believe that OTSAV does this but i maybe wrong ..look at there support forum if you own this software.
PLEASE NOTE CONVERTING KARAOKE FILES MEANS YOU HAVE TO GET PERMISSION FROM THE MANUFACTURER (zoom and laughing Gnome have given us permission to convert as long as you own the originals)AND ALSO LOOK AT THE PRO DUB LICENCE TO SEE HOW THAT APPLIES TO YOUR SITUATION.
