DeckLink Quad for synced playback

Does anybody know of a software that will allow synced playback of 4 separate videos from a DeckLink Quad?
I know that Renewed Vision has a solution - ProVideoSync - but wanted to see if anybody else knew of a solution.

I work on large multi-screen productions quite regularly and use various media servers (Delta, Vioso Wings, Pandoras Box, Watchout, and ProVideoPlayer) but I am looking for a software solution (preferably Mac) that will give me at least 4 channels via SDI.

Thanks,

Brandon

Check out Softron OnTheAir, http://www.softron.tv. It is both software based and for the Mac

Renewed Vision's ProVideoPlayer doesn't output to SDI, so you would need to convert externally for that.

Their ProVideoServer app can deliver synced playback (and recording) through the Decklink Quad card.

i think caspercg should be able to as well and its free !
