Yea, Riva doesn't stretch video. Maybe there is option to do it, haven't checked. I have re-uploaded movies with better quality , 1500k vs 1250k. Also I archive is smaller because there were videos from RA somehow, lol.
EDIT: RIVA can stretch if I run it from WB.
EDIT2: Here video is played in Fullscreen without any black borders at all. https://mega.nz/file/I81x1YgI#EYVeRLngQj82tDNuuOV30qwfTgWlULRErMqtIus0D3E
