Ok, thanks to richUK I now know I can play my Media Center files.
My next (and hopefully) last problem is how to connect the TV live to my CRT telly, which only has SCART not HDMI.
Now, I have an Arcam Solo Movie, which is connected via SCART to the Telly, leaving one spare SCART socket on both the telly and the Arcam.
But the Live TV only has composite, component or HDMI sockets.
So can I connect the Live TV to this CRT telly, or via the Arcam?
