We also have an official 2 yr subscription. Last week you could select the XDream channel it would show a picture for a few moments then totally freeze and we would have to reboot our DM7000S completely. It totally corrupted the unit. Now the channel is decoding but keeps breaking up into a mosiac type picture, but at least it's not completely shutting down our unit.
How would we know if the channel has moved?
i have official 2 year subscription and noticed earlier today that it is not clearing.
I can only assume they are working on something and will wait a few days to see if it comes back.
If not I may re scan Hotbird and see if the channel has just moved
