Thanks for all your help, I really appreciate your effort in finding a workaround.
Unfortunately, with the amount of sequences I have to work with, it’s going to be too much of a pain to click every sequence manually and create a metaclip.
Hope you get the DPX import sorted out.
Oh, and by the way, I stumbled over this:

DPX Components v2
Description reads:
With the Quicktime Player Pro you can import DPX file sequences to create Quicktime movies which you can convert and save to other Quicktime support formats.
Maybe that could help?
