I found the video size window too small. This patch makes the video display larger.
It also adds a video thumbnail, if it exists. Tested only with stopdesign theme.

Sure. Save the patch into your zenphoto directory. Open a terminal and change to your zenphoto directory.
Run:
patch -p1 < zenphoto-1.1.5-bigvideo.patch
You should get a message saying the patch was applied. Let me know if it asks any questions -- it shouldn't.
If you dislike the change, you can revert the same way:
patch -p1 -r < zenphoto-1.1.5-bigvideo.patch
Afterward, you can delete the patch file, and the .orig files.
