Hi Don, thanks for your response.
We are able to export Media using the XDCAM codec. However, we are trying to export directly from Premiere to an XDCAM disc. In FCP7, there is an option in the Export dropdown to export to XDCAM, but this feature does not seem to be present in Premiere Pro CC.
This is how it looks in FCP7: 
We have tried Export -> Media and setting the destination for the XDCAM disc, but this doesn’t work.
Any further assistance you can provide will be appreciated.
Ben
