What I see is the image you refer to for a second or two, and then this:

Click image for larger version.  Name: Placeholder is different size to video.jpg  Views: 56  Size: 86.0 KB  ID: 128365

The black space above your video indicates its placeholder is not proportionally sized exactly to that of your video; this can occur when you resize the Xara Media Player widget by dragging the handles.

Two options here: (1) play around resizing the placeholder until the black spaces disappear - a bit tiresome, or (2) edit the widget's W & H from 100% to your choice, but definitely in proportion (exactly) to the original video. Then, with the placeholder / widget selected, manually adjust the placeholder W & H in the control bar to be EXACTLY the same as the W & H in the widget.

When you preview the outcome, be sure to check it in Chrome & Firefox - I would expect then to see the video as it should be and not jump from your black box to its start position.

It is from my experience a widget resizing querk. Doesn't work every time, but maybe worth a try?
