In MP-TVSeries plugin, we use a Filmstrip view. I noticed that when subscribing to GUIListItem.ItemSelectedHandler() the event gets triggered twice once you start scrolling past the defined scrolloffset range as defined in the skin e.g.

StreamedMP uses a scrolloffset of 4: <scrollOffset>4</scrollOffset>

Once you start scrolling past item 4, item selected event gets triggered twice. Once for the current item before moving and then again for the item that is finally selected.

Steps to reproduce the problem.

1. Create a FilmStrip control in active skin with a scrolloffset defined
2. Set Facade to Filmstrip (GUIFacadeControl.ViewMode.Filmstrip)
3. Subscribe to GUIListItem.ItemSelectedHandler e.g.

GUIListItem gli = arg.Argument as GUIListItem;
gli.OnItemSelected+=new GUIListItem.ItemSelectedHandler(onFacadeItemSelected);


4. Start selecting item by moving right/left

Result: If item selected is before the scrolloffset or after (ItemCount - scrolloffset) then onFacadeItemSelected is only triggered once. If its inbetween its triggered twice.

It should only be triggered once regardless of scrolloffset.
