CDA to CD+G

Hi to every one, I am new to this forum.
I hope that some one can help me.
I have just got Power CD+G Burner, but the thing is that when I try to burn my discs I have a problem. I have got Karaoke oridginal CD+D discs, but when I try to burn them to disk I keep getting discs with NO audio. I think I know what is wrong, when I look at the oridginal disc on my PC, it say’s it is CDA format. So what I need is a way in converting the format of the disc from CDA to CD+G. So any one know of any free software that can do this for me. I need this as soon as poss, as I am doing this for a charity (The Peto Institute) in Hungary that my nephew needs to go to.

Bye for now, from John
