It's A Digital Disease!

I copy the url of youtube channels so that jdownloader2 can grab all the videos and, by keeping everything as disabled completed downloads, I can use the "don't add already downloaded links" function to only download the new stuff.

However, unfortunately, from time to time some old stuff will somehow become a "new" download and be at risk of being downloaded again. (this is not just a problem with youtube, many other platforms too).

What method do you recommend to prevent downloading and storing duplicates? Unfortunately the files generated will also not bear identical names because of changes in quality / codec and possibly also channel owners changing the titles.
