You'd have.to.ask the author

Codecs are finicky

Best bet do it on a pc

Xbox isn't meant to download external files it's sandboxed for a reason

It's not.meant to multi task

You doing an operation that isn't supported

One app at a time

Since you are trying to do something it ain't supposed.to like open an external app from within an app

And app Association isn't supported

That's a pc or mobile feature

Now there is a wok around

Download vlc and do a media scan and hope the codec is supported.not.a hidden virus inqhich case you aintngoing to play it

Some movies are hidden exes which consoles can't rum forcing you to download.their virus embded exe unde the context of a custom rare codec

On your Xbox App, click on the video you want to download. Click on the Share button (a sort of square with an arrow coming out of it) and one of the options is "save". This will save the video to your phone's memory. This is how I have done it on my iPhone
X.

Alternatively, upload the video to OneDrive on your console, then download from the OneDrive.

Apologies for the duplicate response, another user edited their post

there still on Xbox video, give me the option to download but when i click on it it say i have used up my license..

i can stream them but not download them??

It also occurs when downloading large files from certain websites. For instance as soon as I choose a file and click download from Envato Elements, the X-box will turn on. Its so frequent that I've had to unplug the xbox when working.

I had bought an old xbox 360 game recently and it wouldnt download i went to xbox.com found the game for which it said i owned i clicked download to 360 when you next turn it on then when i turnned on my one x it showed as available to download in my ready
to install list.
