If you've lost the channels that you watch a lot, like BBC 1, which have been lost in Spain, France, Germany, Greece etc, can I suggest you install TSmedia on your stb. When installed, go to Menu/TSmedia/IPTV/Oneplaylist/All channels, and then scroll to the right till you find BBC 1. There will be two instances there, the second one seems to work best. Probably temporary, but it works.
