Did you get the answer for your question still?

Hi Jonastt!
You can only conform media in Lustre with an EDL.  And since the EDL referenced non standard CMX EDL reel name, you need to make sure to have an EDL (from Avid) that contains a Source Table (i.e. a table of short and long reel name).  This is an option in Avid EDL Manager.  EDL from FineCut pro have this data so no problem there. Just import the R3D footage, load the EDL, hit Assemble and voila!

As far as the XML cut file, there is no relationship between UIDs and Wiretap Gateway path.  These two pieces of metadata are not related.

Let us know.
