XDCAM Browser is the first step in consolidating XDCAM Transfer, PDZ-1 and Clip Browser into one application. V 1.0 does not have all the features of the related apps available yet and handles FCP imports as a foreground process. You might want to stick with XDCAM Transfer at least until the first round of updates is posted. What you do need Browser for is anything involving MXF recorded on SxS cards (PMW-500 etc). All the traditional importing/logging can still be done in the legacy apps.
