Hi Jason,
The Calibrated{Q} XD Decode codec is a QuickTime codec that lets you use/view XDCAM HD, XDCAM EX, and HDV QuickTime Movies on Windows or Mac computers that dont have final cut pro in either QuickTime Player or other applications that support QuickTime. You can download a demo from our website -

The codec though does not re-wrap the MOV files into MXF or MP4 files.
If you have the XDCAM transfer software you should be able to do that - (i.e. rewrap MXF and MP4 files). Is that the workflow you wanted?
