The video is an old one about Katrina. I need it for homework. I have tried accessing it from CNN's website but CNN in their infinite wisdom put DRM on the video that is publicly available, and I assume that is why it doesn't work on mull, librewolf, or chromium (all show same error about neon request failed). I looked on the generic torrent sites to no avail. Any response would help, the questions are very specific to the video and it is due soon.
Many old cnn videos are on youtube. You may have luck searching the headline from the CNN page on youtube, especially if it's one of those with no article or just a few lines telling you what to expect in the video.
From the context on the video URL and thumbnail, it looks like it's "Soundtracks: Songs That Defined History (2017) S01E04 Hurricane Katrina". I was able to get a hit on 1337x.
If you had time I would say to try contacting CNN directly. Most news outlets don’t mind sharing old reports. Can take a while though.
Another option would be to contact the reporter who did the report as they might save such things for whatever reason or might be willing to put you in touch with the outlet’s archive department, but again might take a while.
But since time is an issue, YouTube may be your best bet.
I think it may be drm'd and gone. On librewolf I got a popup to enable DRM before it showed the error. I thought it might be that whatever backend is hosting the video might be down, and the DRM was a mostly irrelevant complaint.
