@jDoX: Your rules are wrong.
DownloadURL -> this is the final URL that leads to the downloaded file/content
but the videos/content are NOT hosted on this domain!
That's why I use sourceURL in my example rule.
Example: you posted mediafire link here. DownloadURL is mediafire BUT sourceURL is board.jdownloader.org because that's the website where this link is posted.

Also please know that you specify filter/rules that tell JDownloader what to filter/block.
So for example your first rule blocks all Videos with name BLOGGER-video*.mp4 with size bewteen 1 and 980 mb and are hosted on the given domain. But those video are hosted on complete different domain!

Also please just specify the domain and leave alone the procotol else you will either have to use regex to support http and https or create two rules to support both. leave alone the procotol and it will work as well.

Just create a rule like explained

file type - is not - drop down(video file)
and
sourceURL - contains - blogspot.com

That will block all files that have blogsport.com as sourceURL that are NOT videos
