Vogone reduced songs sound different on a Karaoke Player

[Lauraine Graham- with the Lord]

I am new to these processes soI naturally assume I am not doing it correctly. I have created 6 CDG songs which play beautifully from my hard drive. However, when I burn them to disc and play them in my player the vocals, which have been removed using Vogone 2, are clearly audible. When played from the hard drive the vocals are acceptably low in the mix. I am so disappointed. I really wanted to show off my production to my karaoke friends, but at the moment I will have to leave them on my computer until I know how to solve this problem. Can anyone help me please?
