All values are in milliseconds.
The values determine how often the autodetection script will scan video for changes in aspect ratio under different circumstances.
Using shorter intervals can cause lag and increases resource usage.
Using longer intervals increases delay between aspect ratio changing and said change being detected.

<p>In order for autodetection to work, the extension grabs a frame of the video you're watching and takes a look at it.
Some websites use DRM, which prevents you from using the HTML5-blessed way of getting a frame from a video.
Some browsers offer some features that can be used to circumvent DRM protection.
With this option enabled, the extension will use said features to basically do that.
</p>
<p><b>Technical details: tl;dr — only works in Firefox and maybe its forks.</b><br/>
Fallback mode depends on two things:
<ol>
<li>Attempting to grab a video frame from DRM protected video stream must return an error (Chrome returns black image)</li>
<li>Supports <ahref="https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/drawWindow"target="_blank">CanvasRenderingContext2D.drawWindow()</a> method, which pretty much only Firefox does</li>
</ol>
</p>
<p><b>But I thought it's <ahref="http://www.dmlp.org/legal-guide/circumventing-copyright-controls"target="_blank">illegal</a> to circumvent DRM?</b><br/>
Courts <ahref="https://arstechnica.com/information-technology/2010/07/court-breaking-drm-for-a-fair-use-is-legal/"target="_blank">disagree</a> (at least as far as our use-case is concerned).
At this point I'd also throw in some choice words about DRM and everyone using it, but AMO gives me "you're breaking terms of conduct" warnings over use of the word for thing you flush down the toilet, prepended by a word for male cow*, in the code comments.<small><br/>*'cow' is term for the female</small>
