Hi,
thank you very much for your help. I tried both of you methods and it's
working really great but there is one thing left that should work. With my
old (buggy) version the Files from the Treeview were removed automatically
when the encoding was finshed. That means. I have a treeview with let's say
3 titels and after the first title is finished with encoding it should be
removed to only 2 are remaining and so on ...
Any chance that I can manage it like in the past with?

		this.menuListStore.GetIterFirst(out iter);
		this.menuListStore.Remove(ref iter);
