I am still working out the small glitches after upgrading to 2.7. I cannot find where the width of the right hand column on the video_view page is controlled.
I can make the video player wider, I can change the widths of the headers in that same column. But I cannot make my right column move up tight to the video player column.
In 2.6 I even had spaces between my ads but now they are pushed together by some force controlling the column.

If you want to see, just click on a video and notice the wide space between the columns.
