One of the most requested features we’ve received was the ability to add HTML to the slide captions. We’ve added some code that does this, but this means that it ALSO adds the html for stuff like images and videos. In your case this means that the video’s you have embedded at the beginning of your post have been included.
The next release of CBOX will completely overhaul the slider and fix this issue whilst still giving you full control over the captions displayed in the slider.
In the mean time I’d advise you to add a short introduction text (this will also show up in the slide caption) and then display the actual video a bit later. Sorry for the inconvenience!
@gdavis0007: We’re still using the same script for the slider and maybe the longer loading time was related to lifting the limit of slides shown. The [..] is introduced because of the changes made to how captions are made. If you have any feedback on what you’d like to see in the updated slider you can leave your ideas here: https://commonsinabox.org/groups/cbox-developers/forum/topic/cleaning-up-the-slider/
