Thanks Sacha,
I originally used the intro video file on the website and then had the 360 completely separate but the video downloading was so slow at most times of the day it was a joke. It was only 13mb in size so that's why I switched to letting YouTube look after it all as there seems to be less streaming issues.
Silly me, many times I miss the obvious and never even thought to try using the original video 'inside' the 360 as a layer. May well be the solution especially as there's a onvideocomplete="" at the end
Will need to sort out some sort of loading bar as after checking the inline Videoplayer example, clicking the play icon the screen just went darker and then nothing happens at all until the video is loaded. I think most would think something is wrong after 10 - 15 seconds of nothing and head off somewhere else.
I'll try tomorrow and update this post which may help out Virtual Pete.
Thanks again.
