I may have misunderstood the requirement but why didn't you just use the :after pseudo class on the anchor and it will be part of the anchor anc clickable?
Problem is you have to use z-index to get the parent of the img to display over the top of the image, but still have the <a> clickable. So you have to use something like this:
margin: -28px 0 0 -10px;
background: url('../img/tv_play.png') no-repeat;
