what kindof projection/output system are you using?

Were going to a vision mixer so they can add some closeup cameras and then to a Barco Led Wall.

Ahh! You'd think wouldnt you! Sounds like american companies bringing a little bit of NTSC to europe....
Were coming straight out of the scanconvertors I think, I didnt set them up, and there not mine, I'm a newbie with catalyst ( and macs in general! Hears hissing stage right )
Thanks for your help, seems theres not a lot we can do, but I'll fiddle when Im in again and see!
