DKD to mp3+G or VCD

I searched and found articles about DKD files convert from here and I have few questions would like to ask for consult. I got a disc with DKD files and I'm trying to retrieve the song and lyrics to other formats as like MP3+G or VCD due to I want to use those songs in other Karaoke player.

How can I convert the DKD files to other formats I need? And I test the COB2MIDI.exe under Vista OS, but it doesn't work, does it only support winXP?

Thank for your help and really do appreciate anyone who could help and reply....
