I have RAZR M. When I start the podcast, the navigation keys have as long as a two minute delay from when a button is pressed to when an action is taken. I never stream podcasts so this behavior is, for me at least, only present on downloaded podcasts.

This is highly annoying, since I usually listen to podcasts while driving and can't spend time playing with the controls on my phone. I usually like to back up my podcasts 30 seconds or so in order to reacquaint myself where I was in the podcast when I last stopped it.

The behavior manifests by simply not doing anything when I press the buttons. For example, I start Podcast Addict and select the podcast to play. Once I hit play, the podcast starts. I hit the back button once or twice and nothing happens. Sometimes a few seconds later, but usually minutes later, the podcast suddenly skips back, finally registering my button presses. Subsequent button presses usually are real time, but when the player initially starts there is nearly always this delay.
