Firstly, many thanks to Ted, Tmtomh and you all. I'd previously used a PS3, but this is much better, as I can rip directly to the mac. If it is of any help to people I have a Oppo 103D, with a Bluraychip.dk mod (nightmare mod install, but that's for another thread). I had an initial problem the USB Fat32 config, using Disk Utility, the Oppo tray would not open. Reformatted through windows 10 emulation Fat32, it then worked straight off. Ripping fine, if not a little slow over home network using ISODSD. Much appreciated!
