Take a look at “On-the-Fly PlayReady Encryption Using Server-side API” section in [this article](https://www.wowza.com/docs/how-to-secure-smooth-streaming-using-playready-drm-silverlight%28Silverlight%29).

The checksum is in the wrmheader. I do know the play ready sdk to know how to generate this value.

It means there was an issue with the DRM. You can try these steps:
1. Right click on the playbar in the browser window containing the errors.
2. Select ‘SilverLight Preferences’.
3. Go to the ‘Application Storage’ tab.
4. Select the entry “http://[Your-Domain]”
5. Click the ‘Delete’ button to remove stored files associated with that web address.
Note, this does not disable storage, it just deletes currently stored files. Think of it as ‘clearing the cache’ for this website.
1. Repeat steps 4 & 5 for any other entry in Application Storange containing [Your-Domain] in the address.
2. Reload the browser window.

Could you please guide us to where we could find/generate this value:
- smoothstreaming-playready-checksum: This is a special checksum of the key ID that is needed to authenticate the player.
We are running our own PlayReady servers.
