Download the XBMC app for Android. Then go and enable the "The Trailers" addon under "Video Add-Ons".
Thats the only way that I have found to play them. Works flawlessly. Only thing is that you have to adjust media volume to max before you get into XBMC as once in there volume buttons only adjust XBMC volume and not system volume. You can choose which trailer or clip to play, as well as choosing the quality of the stream. Streams 1080P effortlessly as well on my Nexus 4. I'd recommend finding a more touch friendly theme than the stock XBMC theme though, as items are very small. Even with my fat fingers though I had no trouble.
