works but not like it should

This does add a video to the gallery but not in the row below the main picture.
Once its playing it keeps playing even when you choose another picture.
And because it does not show in the row you can not select it again

Refresh page would do the trick but by then my customer is on the highway to the next webshop.

So unfortunatly because of the chance of loosing customers i have to give it a 1 star rating.
for functioning i would give a 2.5 star rating
