Apologies for resurrecting an old post, but I've been having a similar issue playing back MXF's with one of two mac pros that are similarly specced using the latest version of Premiere Pro 2017.

MacPro 1:
Mid 2010
2 x Quad-core 2.4ghz Xeon
22gb RAM
GTX 680 2gb

MacPro 2:
Early 2009
2 x Quad-core 2.26ghz Xeon
24gb RAM
GTX 660 2gb

Mac Pro 1 plays MXF files perfectly smoothly on the timeline. The same files in the same project on MacPro 2 play for around 3 seconds only before becoming choppy and completely unwatchable and certainly not editable.

Although MacPro 1 is newer with a slightly faster processor is has less RAM. The only thing I can see that might make the difference is that 1 is using a GTX 680 and 2 is only using a GTX 660. Could this really make the difference between perfect playback and none at all??? Or could there be something else going on here?

Both machines are sourcing the footage from a very fast networked server, so disc speed should not be an issue, they are both capable of playing back timelines with multiple layers of raw red footage, so I'm puzzled about the massive difference in MXF performance.

Any ideas folks?
