Block is adding extra wrapping div

[dtan]

When I enable this block, I get an extra wrapping div around my video elements:

<div id="video-container" class="">
    <div style="text-align:center;">
        <!-- Begin VideoJS -->
        <div class="video-js-box">...</div>
    </div>
</div>

When I don't enable content in the block, I get this output (as expected):

<div id="video-container" class=""> </div>

Do you know where this rogue wrapping div is coming from? I can't seem to find it anywhere.

after digging around some more, it seems that this was an issue with another, similar block installed. i have since been able to see the offending div not being published to the html source.
