Thanks. Unfortunately that software is the U1 utility used for formatting discs & upgrading the firmware, etc.
“This new utility allows the affordable PDW-U1 drive to both read and record XDCAM MXF SD and HD files with XDCAM Prodisc media from/to either Windows or Mac platforms, as well as, providing general utility functions for the PDW-U1. The PDW-U1 directly supports all codecs, resolutions and frame rates available in the Sony XDCAM Optical Disc family including SD DVCAM 25 Mbps, SD MPEG IMX 30, 40, 50Mbps, HD 420 25Mbps, HD 420 35Mbps and HD 422 50Mbps.”
Perhaps they mean is that the newer version enables writing to disc from NLE platforms. One can also now write data to the “general” folder on the xdcam disc.
