OK, I downloaded JEmplode 2 and although it got further I didn't complete a cloning operation. It came up with some errors and then had a problem restarting the new player. I'll run it again tomorrow and make a note of the errors. I notice from another thread that you've done some work on the Ethernet broadcast code. I'll download the latest before I try again. Incidentally I did have some problems at first with Ethernet broadcast but then it just worked .
