Today, I have been getting a lot of ERRNO 22 errors while trying to download coursera files. Once the Video files are downloaded, they seem corrupted (cant play the full videos). Bad part is, if there is an existing video. first it says skipping, but then says, corrupted and downloading the new video, and downloads the bad one and replaces it. I know the file it overwrites good because I had downloaded previously without any error, it used to play just fine.
