Hi
I somehow new that you would ask me that, so I went and had a look at the app in the app store, and took the tour, as well as checking out one of the videos available for playback in the tour.
When you first hit the "play" button to download and play the video, the vid window pops up with a little button in the lowest part of the window that progresses from the left to the right as the video is downloaded into the buffer.
While there is a "play/pause" button to the left of the "buffer" if you hit the "play" before there is sufficient reserve in the buffer you will run out of reserve before the video completes.
If you allow the input flow to run it's course, without initiating the "play/pause" button, the video will begin playing when it assesses that the play to completion is balanced by the rate of input feed.
Just by the way, I hope your data contract is well padded enough to cope download overload.
Just by the look of the app, it's content, and daily refresh, I reckon Rupert Murdoch will be buying Verizon and AT&T, both shortly. There is lots of gold in "them there hills".
Hope this helps
