Get Help & Advice on Installing & Using Karaoke Software by Power Karaoke

So if I want to use a DVD format karaoke song on my computer, all I need to do is have a host program that will read it? Does Siglos or any host program play DVD content?

Is there an issue with ripping DVD to MP3+G? Is it something being considered or is it something that cannot be done easily?

I was looking through the various programs and was unable to locate one that would rip songs from DVD. I have been looking to purchase DVD karaoke and don't want to buy until I know what program will work. I currently own Power CDG Burner and RoxBox Converter.
