FYI, ProTools LE will not import/export OMF files without also buying DigiTranslator for $495.00.
And on top of that, in order to use DigiTranslator, you must then also buy an iLoc USB dongle.
Of course if you want full video support with time-code and such, you will then need to purchase DV Toolkit for $995.00.
I just love how Digidesign/Avid takes care of their customers!
