Hi,
sorry, I couldn’t reproduce this error (WP 4.5.3, SVQ 1.2).
Maybe it’s just a temporary issue with your filehosting server? Did you check if the files are reachable by entering the urls directly in your browser?
Please do a check with different external urls, like this one: http://download.blender.org/peach/bigbuckbunny_movies/BigBuckBunny_320x180.mp4
Here is my video: http://media-vissarion.ru/media/video/Masterclass%20SD.mp4
I tried your video and it works!
…And I found the problem: the plugin stripes out the spaces in the name while WP doesn’t.
For me, the plugin is OK, thanks.
Thanks for your reply.
The plugin sanitizes the manually entered urls (and all other input data) before saving. In your case, this causes the encoded space (%20) to get stripped.
As the input data should be safe and sanitizing might not be absolutely necessary here, I’ll probably remove it in the next update of the plugin.
