hey mate, i just got a 200 and posted about the same problem yesterday.
This is the solution from Robin Probyn:
“Not an editor but had the same issue come up when I started sending 50 Mbps files from PMW500.. everyone is used to the BPAV folders from XDCAM EX but on one could deal with the 50 Mbps files in FCP.
The L +T doesnt seem to work for UDF folders ..
Answer seems to be XDCAM browser.. set pref to FCP7.. see the clips in Explorer window.. select all. right click and import to FCP.. also read recently better to start XDCAM Browser from FCP.. otherwise its in standalone mode,not plugin mode..
Now with the PMW200 being used I guess alot more than the 500.. Im sure this problem will come up more with FCP .. ?”
Now just have work out how to fix the excruciatingly slow transfer speeds
