Thank you for providing these details, Mebbs. As mentioned, anyone else getting this error please also provide answers to the questions above so that we can fully diagnose and troubleshoot the issue.
I wasn't able to find any documentation regarding the error code, but here's some things that generally fix issues with Xbox Video on the 360:
- While on the dashboard, sign out of your profile (Guide button, then X)
- Go to Settings -> System -> Storage -> Memory Unit -> Profiles, select your GamerTag, and select Delete. Select Delete Profile Only.
- While under Memory Unit, go to Games and Apps, and delete Xbox Music And Video.
- Still under Memory Unit, go to System Items and delete Marketplace System Data.
- Go back to Storage, where it shows Memory Unit, Cloud Saved Games, and other storage devices. Highlight Memory Unit and hit Y (Device Options) and then select Clear System Cache.
- Restart your console.
- Select Download Profile (all the way to the right from all of the profiles in the list).
- Once signed in, try the Video app again and see if that fixes things for you.
Let us know how it goes!
