I finally got it to work... although I just went down the hall for a few minutes and the screen shut down on me! My issue now is that I can't get an XDCAM EX clip to load. This is an mp4 file 1080x1920 from an EX1R camera. I can load SD clips okay. My other problem is the learning curve... the workflow on this editor is a little different from what I am used to!

I thinks that post will interest users of matrox and Lwks .

For a best compatibility, you can copy and paste file LWD corresponding at your matrox I/O in :

C:\Program Files (x86)\Lightworks\DSX

and juste change the name of LWD file with your current matrox software.

And matrox utils does not prevent the opening of LWKS.
