Try this:

files = Hash.new { |hash, key| hash[key] = [] }

Dir['**/*.avi'].each do |file|
files[File.dirname(file)] << File.basename(file)
end

Not sure how you want the output formatted, but I believe that creates
the data structure you're looking for:

irb> pp files
{"movies/film1"=>["film1.avi"],
"movies/film2"=>["film2.avi"],
"movies/film3"=>["film3.avi"],
"tv/mad_men/season1"=>["episode3.avi", "episode2.avi", "episode1.avi"]}
