Hi there!

I need to include videos in articles to show some machines at work; I choosed allvideos to do this because I read that it can be viewed from tablets and mobiles but I'm not able to achieve this goal.
I have a simple mp4 video loaded direcly from standard video folder (syntax: {mp4}video_title{/mp4}) and the video has been encoded by Handbrake choosing the "iPhone & iPod Touch" profile.
The video plays right from PC but nothing to do with iPhones and iPads... what is wrong?
To better undestand, this is the page i'm workin' on: www.mecal.net/index.php/it/prodotti/product/view/11/26
Thank you all!

PS: there's a way to choose a preview image to be shown when the page is loaded?
