New issue 77 by jacobmo...@jacobmoore.co.cc: vreverse.py example fails
http://code.google.com/p/echo-nest-remix/issues/detail?id=77

What steps will reproduce the problem?
1. cd to location where both vreverse.py and the video to reverse are
located.
2. type python vreverse.py beats infilehere.mp4 outfilehere.mp4

What is the expected output? What do you see instead?
It should work, producing a video file that is reversed. However, I get an
error about unsupported operand types (full output in the additional info
section below).

What version of the product are you using? On what operating system?
I have the latest echo-nest-remix installed (The Echo Nest Remix
API-1.4-py2.6-macosx10.6.mpkg.zip), with python 2.7.1. I am using OSX Lion
(10.7.1).

Please provide any additional information below.
Other scripts like the swinger.py and summary.py scripts work fine.
