Hey,
I found a bug with gjr's new zpbase theme. It seems that the right/left arrows in the image detail page steal clicks headed for videos, which means that there's no way to actually hit "play" on a video. This can be seen on the oswebcreations site here: http://oswebcreations.com/video/manofsteel.mp4

When I click on the "play" button, either the right or the left arrow is clicked instead (depending on exactly where the mouse is positioned).

Configuration:
zpbase v0.92
zenphoto 1.4.5.9
Firefox 29.0 / OS X 10.9.2

You need to click the play button on the nav bar at bottom of video. The play button that's in the video frame is covered by the nav overlay.

Thanks guys - I will get a fix rolled into the next release for this...
