Hi. I have an old Phillips On Digital box that is tune into the old stations. I can recieve BBC1/2, ITV1/2, 4 and 5, but not the other freeview chanels. If I try 'auto update' it comes back with an error message. If I try searching for new chanels it stops halfway and will not save. How can I update this box and get it to work properly? The signal appears strong with clear pictures on all the chanels I am recieving at the moment. Any suggestions please?
