Most clips come in through the XML import just fine, however there are a few clips that for some reason count from zero at frame one. In the project settings I checked the box to Use Timecode From the Source Clip Frame Count. However it still ignores the clips that count from zero. Wrong Extents.
If I was in FCP I would do a force re-link and it would be fine, however in Resolve, the clips with missing media have no visible options for replacing the media or pointing the blank clip to a specific file.
