Official BS.Player forums - Problem with overlay renders

Hi everyone!

I'm having a problem I can't find the solution to. Everytime I choose any render with overlay, the picture will not fill the whole window, but occupies only a quarter of it, on the top-left corner.

The reason I want the overlay is because I'd like to have the subtitles on the black frame below the picture and it is the only way I could find to do that. I'm pretty sure the overlay worked before, but I don't know if I've touched anything and now I can't get it to work.

Any ideas?
Thanks!
