I was adding some channels to a bouquet and noticed that after selecting the bouquet to add the channel too, the highlighted channel was no longer visible in the channel list, i had to scroll down to get to it again.
Procedure:-
from 'Satellite' channel list, cursor down to a channel, press menu, then select 'Add to Bouquet', bouquet list is displayed, select bouquet. The satellite list is displayed but the initially selected channel is no longer selected.
