When watching Blu-ray .m2ts (1920x1080) files wrong size is scaled horizontally. Remain strips on the left and the right. Scaling mode - fit. If scaling mode - full, size becomes correct, but other files rip .mkv and other with the size different from 1920x1080 example 1920x866, wrong scaling! Stretched to full screen! And why when watching Blu-ray information shows 1088 instead of 1080?
For 1088p I can answer, 1080p is not divisible by 16 and h264 work with 16 pixel square, but usualy player ignore the 8 pixels over.
Thanks! Then it turns out the fact that in 1088 reduced to 1080, respectively, in proportion to the decrease in 1920, so there are vertical stripes on the left and right! @mirror, @freeroc fix this problem!
