My setup is "usals" set to "simple"

Using Bouquets especially, my 800 just sits there until I choose another channel on the same sat then bingo.

If I go to Premier Sports Portal on 19e from say BBC1 on 28e it just sits there if i then choose another say Bundesliga 1 bingo. the can happen going from 13e > 1w or 13e >19e. 28e is better but can get "stuck".

Thoughts?
