Hi Amy,
This problem has actually seemed to resolve itself with new versions of Adobe Premiere. I imagine the newer versions export a more complete XML. Im using the latest version of CC 2015 now and don’t have problems with it. The workaround that I found was most efficient for me was to make a full res (prores 422 for me) export of my cut. Clean, with no cards or titles. From there i brought the video into resolve and used scene cut detection. It’s a very useful tool, if you aren’t familiar with it it might be good to look up some tutorials online. It’s fairly easy to understand. Hope this helps! I struggled with this problem for a long time and tried many different things.
Best,
Eduardo
