I don't quite know how I got there, but I have now found Microsoft Windows Network, but all that is showing is "Mshome" and within that shared folders for other computers in the house. Am I correct in thinking that the Humax should appear in the list with Mshome?
I've never used that command before, but it would seem to need the "\media" on the end to work.pushd \\192.168.x.x
