I need the universal code for embedding a video in an email and have it set for autoplay.
So that when the user opens the email, the movies starts playing imediately.

Aprox 10 seconds of video and sound.

Those codes aren't given out to just anybody because spammers would be in heaven should they get ahold of one. Until you're deemed worthy and receive your code, the only way to send video by email is by joining a service designed for sending video by email, or attaching a video file to the email itself. Neither option is particularly welcome by recipients without prior notification. Dialup and other low bandwidth users especially will curse your name if you send them a 10 second video that takes them 12 hours to download.

A better method is to host the video on your own web server and send a pretty HTML formatted email message that contains a play link or embedded play control to the video on your server.

It really doesn't matter what you want to embed in an email, if the recipient's email settings are not set to HTML be default then it won't be seen. Due to incidents of abuse in the past most are NOT set to HTML by default.

I see. Well Ive been able to do that.

What bout embedding a sound clip to autoplay in the email?

Embedding any auto-executing content is going to require special support to do so because the security risk for the recipient is too great. Your video or sound clip could just as easily be a virus that erases their whole machine. And frankly, given the recent published flaws in Adobe Flash and Windows GDI components, and the increasing sophistication of spam, I'm contemplating alternatives to email and/or sandboxing it before allowing messages to reach my personal machines.

I think the only way for multimedia/other embedment to become commonplace is with IPv6 and an infrastructure that doesn't allow for anonymous senders.
