Since you posted this question, I addressed that Transparent check box in the Border and Background Color Pickers. We have not had a chance to prove it works. If someone sophisticated enough to have a Transparency capable CDG player and external video mixing equipment wants to try it, please post your results here.
danny_g, after your post above, I fully described its operation in the 2.009 manual. Thanks for pointing it out to me. In Karaoke Pro, this functions correctly as described in the manual.
