Something that has been killing me is the need to convert the Output of Catalyst into HD-SDI. This is especially true when I need to Genlock to a video switcher.

I prefer to use Fibre extenders whenever I link directly to a projector. I also use good old RGB-HV. (You'd be surprised how far a 5-wire run can be on 4GHz copper.)

However, my specific needs are for an HD-SDI solution.

Obviously I use ImagePros but this can get a little expensive when running a dozen or so projectors into an HD-SDI system.

I have also used the Gefen DVI to HDSDI Pro Scalers and Scaler Plus. These things are a major pain in the a$$ though. Their genlock totally sucks and hops a half frame out of phase constantly in an HD system.

What I would like to know is what everyone else is using. What works?

Has anyone used any of the HDMI to HD-SDI solutions from DVEO, AJA, Thinklogical, or BlackMagic? How about any other DVI (or even VGA) to HD-SDI solutions?

Your feedback helps, thanks.
