Managing Access to Windows Media Multimedia Redirection (MMR)

VMware Horizon provides the Windows Media MMR feature for virtual desktops that run on single-user machines and for published desktops on RDS hosts. MMR is not available on published applications on RDS hosts.

MMR delivers the multimedia stream directly to client computers. With MMR, the multimedia stream is processed, that is, decoded, on the client system. The client system plays the media content, thereby offloading the demand on the ESXi host.

MMR data is sent across the network without application-based encryption and might contain sensitive data, depending on the content being redirected. To ensure that this data cannot be monitored on the network, use MMR only on a secure network.

If the secure tunnel is enabled, MMR connections between clients and the View Secure Gateway are secure, but connections from the View Secure Gateway to desktop machines are not encrypted. If the secure tunnel is disabled, MMR connections from clients to the desktop machines are not encrypted.
