Question about exporting XML

(I posted this under the Davini forum originally - but thought maybe the problem I'm having might be what I'm doing (or not doing) in FCP)

This is what I'm trying to do:

1) Create proxy ProRes files in Resolve from original DPX files.

a. [In Resolve] I'm using Scene Detection to split 5 min DPX clips into the different takes within the clip and doing a simple grade for each take.
b. I'm then Rendering out ProRes files for each of the split takes to a new folder.

2) I am then renaming the new clips(files) to its Scene-Shot-Take name: For example: from 164884 to 48C_01_01

3) [Then in FCP7] I'm editing the shots and exporting an XML.

4) [Then back in Resolve] I'm trying to import the original DPX source files for final grading.

But this is what is happening:

When I load the XML and navigate to the folder with the source DXP files Resolve tells me all the newly named files can't be found.

I thought XML linked to the Timecode? I figured as long as I navigated Resolve to the correct folder. It would find the correct timecode and load the correct DPX.

Thanks in advance for any help with this.
