Saw your Posts regarding DMX-R100 and DP.
I am in the same boat. Its just a NO GO.
Wondering if you ever found a way to get a smpte lock so that I can at least use the automation on the desk?
I'm running a MTP AV, and as of yet had NO luck in getting a smpte lock in either direction. I was wondering if this was due to the MTC/MMC Issues you mentioned?
