So I was at the store yesterday and wanted to listen to the 1Up Show while I was shopping.   I started the podcasts and locked my phone so I could put it in my pocket.  The podcast stopped playing.  O…kaaay….  What the heck?  I tried playing it again and the same thing happened when I locked the phone, the video just paused.

I figured I would have to keep the phone unlocked in order to listen to the audio portion of the video, so I just let it go like that.  A few minutes later I checked the batter indicator and it was running low.  Not low enough to worry about not getting a call, but the video playback did eat away at the battery.

When I put the phone back in my pocket I accidently locked it.  Forgetting that I was playing video (I am absent minded like that), I brought up the Lock Screen (pressing any of the buttons on the iPhone after it has been locked) and brought up the iPod Play controls by double clicking the Home Button.  When I pressed play it played just the audio, exactly what I wanted it to do in the first place.
