Try new version 5.6.1.0. It's fine, but Zoom settings are not save after exit the program. There is no that problem in old 5.3 version. I have 16:10 monitor and I always change zoom (Settings->Zoom...) to fit video to 16:10 without upper/bottom black lines. And the zoom settings always save after closing the program. So, I haven't to change zoom on next start. Please, fix it in new version.
