how do you mean? will it not play when downloaded or is the link corrupt? it works for me (there´s a limit on 10GB/day so if you ask for five files á 5GB or more than it will take some time to download)
pixeldrain is the only approved host that has good upload speed and allows big files
i´ve had big problems with uploading to cyberfile (error after 97% of upload) and the speed with mega is, well to put it nicely, slow. i can use it but then you´ll have to wait a couple of days
and splitting files to put them on bunkr, i could do that if and when i have the time
if the files corrupt hit me back
