Nevermind... Just typing out the question got me thinking on different lines. Apparently SurfControl was blocking it, even though the filter wasn't enabled for that rule. I added it in as an unmonitored site and it started working again.

Of course, now that we actually need to utilize that functionality, I cannot get that rule to work again. I've been fighting with this for hours, and still cannot get the video to come through using the exact same methods I got it to work with before. Anyone else working with this?
