video content not playing consistantly

Hi,

I have created 4 slides all with background video content. They look and work well the first time they run but on subsequent run they don’t play or play only a small part of the video.

My test site is here: https://kbmresourcing.com.gridhosted.co.uk/ decent server / bandwidth and no streaming restrictions according to the hosting provider.

I wonder if I am doing anything drastically wrong?!

If you are able to take a look for me I would be very grateful!

regards
Martin
