It doesn't look like you've modified the filesystem in any way.  You need to
grow your XFS filesystem using xfs_growfs.  Since you want all the space used,
it ought to be as simple as:

  xfs_growfs /video

...but checks the docs just to make sure.  :)

Increasing the size of an LVM volume is akin to resizing a simple harddisk
partition.  It changes the partition table, but not the data contained
