Width/Height Doesnt Change

http://keepit100.me/videos/ & http://keepit100.me/musicvideos/ I tried to make it 615×315 cause 615 is content’s width. Well it doesn’t change it remains small. Only time it changes is when I have both on auto (default) and then of course shows the crappy black bars above and under. I want it to fit right into the content.
