DMS-CD Restrictions
•We do not support use of the “Cast” plugin for Digital Media Designer with any content distribution
system or network. (CSCto35473)
•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.” (CSCtn07580)
•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 hard 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.
