Hi, I had mine setup through component because the Telewest engineer could'nt get the Box working through the HDMI, in the setup screen you just need to choose "HIGH DEF" and "component". Unfortunatly as I said,if the program is HDCP (HIGH DEFINITION COPY PROTECTED) you wont be able to view it on component. I managed to get mine working through my HDMI socket after the engineer left, but it was his first set up
