Video size problems when Burning

Hi there, I’m not sure if this is the right place to ask this but I couldn’t find any info on the net otherwise. My problem has to do with making DVDs in Nero and it seems that every time I burn something, it cuts off the top and bottom. This is really frustrating when I’m watching anime with subtitles because it cuts off the text! Of course I’ve tried different combinations with burning it as 16:9 or 4:3 etc. but nothing seems to work. My DVD player also has a TV aspect ratio controller and I’ve fiddled with it and no results :frowning: Is it hopeless for me or could it just be the burner has a hidden button for this kind of thing? Thanks alot
