If CAVs converter can take a file on the hard drive, then the KHPro created .CDG file can be imported directly into it.
Also, our .cdg file extension is the same as the .bin file extension, which many programs support.
We use .cdg because we were first doing PC Karaoke and that is the extension we have always used. 
BIN files often are NOT true CD+Graphics files with the R-W lyrics/graphics codes. Thus, it can be very confusing for users of any technical understand to try and convert a .BIN file that is, for example, the entire disc image file for an audio, or CDROM, or VCD or other disc format... but they won't know that. They try, and try, and... you get the idea.
MTU .CDG files ARE true TRACK image files from a CD+Graphics disc. They are always safe for all user's satisfaction and joy!
