Video not working

in the slideshow options, you must also tell that you want to open your slides in a lightbox. Have you set this ?
for now it is on "same window"

Ah. Thank you!
Yes, setting that to lightbox works. Do I need to set this manually for every slide? Is it possible to set the default to lightbox somewhere?

you can set it for all slides, in the Effect options tab >> default link target >> lightbox

Amazing! Thanks very much. That will same me time!
Just the YouTube video doesn't display in the lightbox. Is this possible?

great
for the video :
1/ show the video in the slide >> in the slides manager >> edit slide >> video options >> give the video url
or
2/ show the video in the lightbox >> in the slides manager >> edit slide >> link options >> give the video url

I appreciate your help and patience, thank you.

I have tried both those options:

1. The video doesn't show in lightbox, just in place n the slideshow.
2. Shows the image in the lightbox, not the video link.

I am using - is this correct?
