I know this is an old thread, but I have a DTR1000 which is a BT box (no badging though) and I cannot get the retail Humax firmware updates. This is how I discovered my box was actually a BT one in fact - i.e. I could not understand how my apparently Humax retail box was getting BT updates when I am connected to Plusnet. Apparently BT boxes have a hard wired identifier code which means they will never get the retail firmware updates, only BT ones. This is what I was told on the Youview forums anyway.
