Just moved into an apartment block renting,had my own sky + box.Got it installed,but the engineer said that because most apartment blocks have only one sky cable and come off a communal dish,i wouldn't be able to record a channel while watching another. Not allowed to start running cables from it or fitting your own dish you see He mentioned that some of his work colleagues were aware of a splitter box that allows you to get the two cable scenario through just the one cable. Has anbody heard of such a device????
