Pangolin uses a combination of MCI and WMP (actually DirectX). We use the combination instead of just one source for our own reasons. As far as I know, our software can do things that other laser software can not do with media, so I don't think there is a problem. Actually, I don't know of any complaints with our implementation.
In any event, of course, future versions of the software will add more capabilities, particularly with respect to video. As one example -- at this past ILDA Awards ceremony, it was actually the Pangolin system that played almost all laser shows, and all video as well. More will be coming soon....
Best regards,
