videos in preview window??

[songpony]

I could have sworn that in one of the recent demo versions, videos could be seen in the Preview window, same as all kma, CDG, etc. songs being played. I was surprised when I upgraded to 4.08 to find that my preview window is just black (as it was in older version) when a video was playing. Is it an available option that I just haven't figured out how to set, or was this functionality removed? If removed, when is it coming back?? As the host, I'm not always in a position where I can see the Singer's Display, so having it on my screen was great. Thanks.
