Hmm, maybe try resetting Channel 1 back to "SKY ONE":
The "factory reset" will reset channel 1 only to Sky One. It will also reset the Installation menu settings. It will NOT change the rest of the channels.
On the remote, enter this sequence:
Menu, 0, Store, Right arrow, Left arrow
(Shamelessly nicked from satcure's old website!!!
)
Then re-enter the frequency for Eurosport, and Store...
Hope that works...
