In diagnosing a problem I was having with a drive slot in my 860 with AE3, I opened the unit and replaced the four hard drive slots with a new StarTech.com 4-Bay Mobile Rack Backplane. While I was in there, I removed the memory modules, cleaned the contacts, and reinserted them. Now I'm having a problem where all videos played through the box have audio that stutters and the video is playing off speed. I'm having the same problem with any other source, including NDI. I did a memory test, and it checked out fine. Anyone have any idea how to fix this?
