DMS-CD Restrictions•
We do not support use of the “Cast” plugin for Digital Media Designer with any content distribution
system or network. (

•
Even though Microsoft Internet Information Server (IIS) is not case-sensitive, any use of IIS can
trigger case-sensitive behaviors in DMS-CD. This occurs because DMS-CD uses all lowercase
letters during its creation of a local folder whose name matches the FQDN of the external IIS host.
When any asset URL includes even one uppercase letter in reference to the IIS host FQDN,
DMS-CD cannot find any local folder by that name and, so, cannot find its local copy of assets to
render. The error message in this case is “Size = Not Available is not available with the File Access
Service. The status is FAILED.” (

•
This DMS-CD release does not support live video. It provisions assets that already exist.
•
This DMS-CD release provisions assets to DMPs exclusively. You cannot target any other
device type.
•
This DMS-CD release does not delete files from any DMP that belongs to multiple DMP groups.
For autocleaning to occur on a DMP, it can belong to one DMPgroup only. Alternatively, you can
use Play Now to deploy a job to DMPs.
•
You can attach only one external USB flash drive or external USB h ard drive to a DMP.
•
We do not support USB hubs or any other method that you might use to attach multiple drives (or
other device types) to a DMP.
•
DMS-CD does not prevent you from using the Actions list or the Play Now feature to start
transferring a DMS-CD deployment package immediately. However, using either of these methods
defeats many of the most important benefits of using DMS-CD. We recommend instead that you use
the Play in Future feature to schedule all of your DMS-CD deployment packages.
•
You cannot use the Deployment Status feature (at Digital Media Players> Deployment Manager >
Deployment Status) to check the progress or status of immediate deployments.
