Xbox DVR not uploading to Xbox live

you need to upload to Xbox live first, when uploaded you will have all the options including a DVR app

If you have a mobile game clip what you've recorded to your phone using a screen capture app or something like that, you can't upload that video to Xbox Live.

Sorry, but that's not the way it works. You can download, edit and upload back
to Xbox Live only those game clips that
you’ve recorded with the Game DVR feature.

Step 1: Upload the video to Xbox Live (what you want to edit)

Step 2: Once it's uploaded to the Xbox Live, download it to your Win10 PC via Xbox App

Step 3: Edit, trim and save the new game clip

• Edit and share game clips with Game DVR in the Xbox app on Windows 10

Step 3: Upload your edited video back to Xbox Live

This Error Code means that you have to many Clips/Screenshots uploaded to Xbox Live and Xbox DVR fails to load them all, so you need to ether remove some Clips/Screenshots from Xbox Live (Those Clips/Screenshots will still be on your Console, just not on
Xbox Live for anyone to see) and if that doesn't fix the DVR Error then you have to delete some Clips/Screenshots completely both from Console and Xbox Live to fix this DVR Error so Xbox DVR will be able to load your Clips/Screenshots about For Honor and other
games.

The account will not be able to upload Game DVR and Upload Studio content to Xbox Live for a specific duration, often 7, 30, or 90 days. The account will not be able to communicate on Xbox Live for a specific duration, often 1, 7, or 14 days.

Go to Skydrive and sign in with the gamer tag's email/password.

Then click on Pictures and then Xbox Game DVR to find the videos.

For some reason the Xbox One uploads upload studio videos under your "Pictures" and then "Xbox Game DVR" folder. It would make MUCH more sense to have it under videos, but that is where the uploads are stored.
