Random question, does anyone know where I can find additional information on the CD-G, CD-EG, or CD-XG disc formats? They seem to be interchangeably called CD+G, CD+EG, and CD+XG. CD-G is a fairly common CD format used for Karaoke that is backwards compatible with regular audio CD drives. Put it into a Karaoke machine and it will play video along with the audio. Put it in a regular CD drive and you get only audio. Wikipedia pointed me in the right direction for CD+G.
CD-EG/CD-XG I haven't found anything on. Were any discs ever made? Wikipedia was of no help.
