When I visited your first URL I got a silent video of a guy paddling a canoe until it
sank. I guess it was supposed to be a sort of blooper video. It certainly was nothing
to upset a prude. VDH did not recognize it. There were some other entries in the VDH
menu, but nothing for the canoe video. I downloaded a couple of them but they weren't
the canoe video. I did find it in the Network Monitor. It took a few page reloads to
make it appear in the Network Monitor but it did appear. It was an MP4. I double
clicked that entry in the Network Monitor to make Firefox open it in its own browser tab.
That worked fine. Firefox's built in video player played it fine. The audio control in
the Firefox player had a line through the speaker icon, confirming that there was no
audio track with this thing. VDH did not recognize anything on the separate tab, either.
Firefox had no trouble downloading it via the Save Video As option on its popup context
menu. Why didn't VDH recognize this? Beats me.
Your second URL was basically the same story. VDH recognized nothing but I got the video
from the Network Monitor & Firefox's download. It was another silent video in which a
CGI creature allows a rock slide to crush a castle.

If you want me to look at something more spicy that is actually NSFW, you have to give me
the link. I am not going to rummage around on the site trying things out at random.
Point me to something specific.
