Thanks Jeremy. No not dropping frames, warning is on. Media is on a raid5 SAS drive tower (proavivo 8 drives) hooked up to a ATTO r380. Atto utility reports everything is fine. But I also have a JBOD sata raid 0 array and shows on that drive also play back funny. Everything plays back funny no matter what drive it is on. And as I mentioned it was all working correctly a couple of weeks ago. Same media, same 10 episodes on the SAS, same 3 documentaries on the JBOD Everything fine then, everything has a lag now.
Only thing I did was update OSX and FCP and update theKONA driver. Have now gone back to the old driver but still have the problem. Should have cloned the drive first… learned my lesson.
