Not sure that I will be able to do that while we are out on tour... I'll try... I looked on the Black Magic site and found a new firmware release that fixes genlock stability and general stability and performance but when I called them they said they had no reports of issues like mine. I'm not certain that a genlock issue would look like this.. though it may in the digital domain once the signal is "in the card". As far as other things that may cause this... are there any system tweaks or other things anyone can recommend taking a look at... the system is flawless aside from this issue and I'd like to get it rectified asap.. thanks
