Opensource is ultimately the way things are going to get much more productive
http://www.openlp.org (the open source lyric projector system for windows) is an example of this, as is
Lyricue the GNU Lyric Display System (For which I created the Lyricue rebranding). There is also the
http://www.opensong.org project (for users with guitar tab requirements).
zionworx 3 is using it's own video engine - but I don't think Christian will want to use GPL code in zionworx because he doesn't want to open source the project.
Which is a pity really since the de-interlacing algorithms are going to be tough to come by otherwise.
It is of course his prerogative since without him we would not even have zionworx at all but I do get the feeling that through having four different 'free' projects addressing the same issues we are risking allot of lost time, missing out on a huge testing base and many other advantages to open source. As this is for a church application wouldn't it be nice if we could all at least share the source and system constructs.
The sad fact may be that Lyric Display will otherwise remain as insular and segregated as the church it wishes to serve. Perhaps this is a cue for Christian to email the other parties and help generate some kind or consortium page which focuses on the developing of on-screen-display for event software.
