Mottiv,
I posted a couple comments to your YouTube videos. It may be the same think Mike is thinking too, but to me this is an issue with the batteries. You can tell from the sound. It starts ok then breaks up and starts to fade. This is typically a sure sign that the batteries are weak and about dead. Do not use the cheap ones, get new Duracell or Energizer that are known to last. Hope this helps.
