screen logo or embeded subtitle

[nyzys]

some widescreen movie especially those in realmedia format, there always are some logo or address such as website on the top of the visible part. Or sometimes some subtitles which we dont need or which is not the languge we want are embeded in the movies, and we can not remove them. Is it possible to screen those logos and subtitles since those black parts in widescreen are always black, so we can put new subtitle on movies and will not be disturbed by those advertisements.

by the way, I think it is better to make the player panel in full screen bigger just like media player classic, so more button can be put on it or even make them customizable. and the process bar can be longer so that the locate operation can be more accurate. a drop menu can be used as a playlist so we can play any media in the playlist without always pressing 'next' button
