With a current disk speed usage of 90 % it is not likely that the Cpu usage could be more than maybe 45 % anyhow. About Quicktime we don´t know that yet , I also think that I´ve heard someplace that Avid is working on that part but now we are speculating. Another drive needs to be used for the linked media to get up in transcode speed though

You seem to have a couple of more threads about your AMD builds, I have answered in one or two, maybe you could continue in one of those. From what I´m aware of Avid wants Intel or Xeon CPU to work best, there should also be a whiteboard about that someplace as well as a list of certified systems but in my own experience also self built systems

And Yes, I do have NBT 4 Ult installed here

Maybe not in 4K mode Carl

[quote user="mtwhalen"] I know this works in 8.x but I can't upgrade until July and would like to work on these files before then. [/quote] Why not, meanwhile , use another system and trial mode of the latest Avid, link and transcode, and move the media to your MC 7 system

No problems what so ever on the Mac side , and the Windows fix comes with 8.8.3

Boris ?

[quote user="Michael from cologne"] MC 8.8.2. always gives error message when shutting down application on my system!?? [/quote] It´s your Matrox unit, Avid broke this with the latest versions , just press OK when you get that message

[quote user="DIESELE"] +! - many of us are STILL sitting on 8.6.5 due to this and the render glitching issue. [/quote] Fix might be close now

The LE works great , also with the latest versions
