TIMTOWTDI:

find Video/* -maxdepth 0 -type d -print |while read fname
do
 mv -- "$fname" /alt/video '+'
done

1) spaces in the name should work because the last arg to read will
pick up all remaining arguments regardless of space.
2) this will work on systems that do not implement print0/-0
3) the -- in mv will tolerate fname beginning with -.
4) the "'s around $fname will allow fname to contain spaces.
5) doing it in a loop allows you to do multiple commands in the loop.
6) be aware that on bash that any variable you set in the while loop
will not be set outside of the while loop.
