dear all, we have a very short digital video tutorial for sale. We would not want it to be copied and sent to other people by early buyers. We would appreciate what to do, to overcome this. We will appreciate workable responses. Thank you.

I doubt if you can really control that but rather depend on the trust of early buyers. This is because if you make it downloadable after payment on your website, it will still take the trust of early buyers not to share their legally bought copy with their friends. If you make it on DVD and sell by postage, just think of entertainment DVDs out there in the market. It still depends on buyers not violating copyright rule. They may still show or share it with their family. The only way I have seen once was a UK website that sold real eBook to me in 2008/9. The document with its embedded videos have login and password to open after payment and downloading before you can read it on your computer. I thought that was all and I could open to read on another system but each requires log on again and validation by their system before you can view. It was real eBook and not the usual PDF we buy and download these days. But then, it still boils down to me not sharing my login and password with others after getting the access.I even tried to snip each page so that I won't need to login each time before reading but not possibly with the embedded videos.

We have decided to make it free @arbitrage
We are developing another business model to generate profit, though it will take time to build a crescendo of good profitability.
Thanks @arbitrage for taking time time to explain.
