XDCAM Disc drive for the PC? This would let you extract the MXF contents to a single MXF file and do what you want from there.
I've used the PDW-U2 on Windows before. It's just fine. We made a workflow to read one or more episodes of content off XDCAM Professional Discs into Grass Valley Edius, trim the tip and tail, and then re-export w/ smart encoding to standalone XDCAM HD422 MXF files which then went directly into playout servers without issue.
I'm sure you could extract the MXF files with the XCDAM Browser app and then use whatever transcoding you want
