When installed it solved 95% of my screen format issues by simply using the default settings. The other 5% you can try to tweak because I know you like it :-) My experiance is that you can not improve very much because the remaining problems are often caused by the provider of the content.
e.a. A movie with black bars, and an embedded subtitel put in the lower black bar. Or the station logo is positioned above the movie frame.
Install en enjoy, you will like it!
