Hi, bumping this old problem. I'm having the same issue and my show is Sunday night (Oct 22 2017). Im running DXV3 clips like I always do, on Arena 5.14 , on a system that's been very stable for a long time. Getting a smtpe signal through the headphone jack from a Protools server with the correct frame rate selected. The clip starts jumping up and back, then plays for a few seconds, but very choppy, then jumps around and back. I've never see it do this before, nor has the sound engineer. Also songs will work perfect one time, then not the next. Maybe its the auxillery cable?
Any other methods I can use to keep these songs synced?
