Adding one more option to what unor already said.
You may consider your video as kind of review (overview of the product). You can even say (depending on your actual web page) that AggregateRating (you have in code)+reviews for it+video are all parts of this broad Review. Then markup may look like this:
<div itemscope itemtype="http://schema.org/Product">
<div itemprop="review" itemscope itemtype="http://schema.org/Review">
<div itemprop="aggregateRating" itemscope itemtype="http://schema.org/AggregateRating">
<meta itemprop="ratingValue" content="5">
<meta itemprop="reviewCount" content="20">
</div>
<div itemprop="video" itemscope itemtype="http://schema.org/VideoObject">
<meta itemprop="name" content="Hello World"/>
<meta itemprop="duration" content="T1M33S" />
<meta itemprop="thumbnailUrl" content="v2.jpg" />
<meta itemprop="contentURL" content="www.viddler.com/player/xyz"/>
<meta itemprop="embedURL" content="http://viddler.com/flash/publisher.swf?key=xyz"/>
<meta itemprop="description" content="Hello world"/>
</div>
</div>
<div itemprop="offers" itemscope itemtype="http://schema.org/Offer">
<span itemprop="price">Rs.100</span>
</div>
</div>
