I have a Panasonic TX-P46G30E and I try to use it as a media player but some files seem to have wrong size and aspect.
for example a 1280x536 mkv appears as 4:3.
I also own a PS3 which renders these files absolutely fine, but I want to use my TV.
I tried to fiddle with the Expert settings, such as
width == 1280 && height == 536 :: -vf scale=1920:804
(as for a correct 2.35:1 aspect), but without succes.
