What I would do is create a new directory. Download a few videos within subdirectories within that new directory using only YT–DLP. Don’t use aria and upon completion compare the whole videos from the new download session using only YT-DLP with the previous one (aria). I would check by playing the files side by side if possible and check the videos’ duration. Check the file sizes and run diff in a terminal with both files provided as arguments. If diff complains of a mismatch between the binary files they indeed differ in one aspect.
