How big can an embedded video be?

I embedded a video here but it won't play. I just wondered if the fact it was a full length movie might make it too big. It's also possible that I naffed the HTML when I turned off the autoplay feature... just wondered if anyone had any clues. Cheers.

dont know. just try you tube next time. wierd the amount of stuff on there. dont stress about what works and what dosent lol

Think I will. The videos might have to be posted in several parts, but at least they write their code properly and don't leave amateurs like me to poke around and make it work how you want.
