DS-7608NI-E2/8P Not working 100%

Yes I did give that a shot, sorry for not responding to you :).

It's been running for about 8 hours now. I've recorded a car coming and going from my driveway without any stuttering!

It's all good. I'm glad that you got it working on your replacement unit. I was more curious to know if what I suggested was going to work out for your or not.
