"The idea here is that you have to press play on the following videos (in vertical order) so that they all stream to you at the same time. You may need to adjust the volume on each respective network, though. Press play on the top (YouTube) video, then immediately press play on the second (Google Video), and then press play on the third (Revver). Bam, bam, bam - and you should see ‘em playing back simultaneously."
