Could you please upload images here and video to youtube. This will be the only way for you to receive the best results. Other wise we are all stabbing in the dark and it's not worth us putting in the effort.
Most video email embeds will only work if your clients are using either, Apple Mail
Entourage 2008, Outlook Mac 2011, MobileMe and iPhone, I may have missed other mail clients but, if the embeds doesn't work there should be a workaround probably a pdf file attachment with media embeds.
