should unblock the communication to permit the application to run. You are safe to unblock the communications because you are not enabling any connection or communication with the Internet, only between the media vault and its software applications.

The following list comprises the software applications that need to communicate with the media vault:

HPMVTray.exe – HP Media Vault System Tray utility

NASSelector.exe – HP Media Vault Browse utility

NASDriveMapper.exe – HP Media Vault Drive Mapping utility

Cddib32.exe – NTI DriveBackup!

Shadow.exe – NTI Shadow

HPEZBKUP.exe – HP Easy Backup

HPMVCheck.exe – Firmware check utility

If any software is reinstalled, moved to a new disk location, or if the application is deleted from the exception list using the Security Center control panel, communications between that software and the media vault may once again be blocked by the firewall.

1.Make sure that your HP Media Vault is powered up and working before you power up your Digital Media Adapter (DMA).

2.Check to make sure that your DMA supports the DLNA/UPnP protocols, which are the protocols supported by the media vault. Some DMAs use proprietary protocols that do not operate with the media vault’s media server. For a list of compatible DMAs, consult the HP support web site at www.hp.com/support.

3.Ensure that your DMA is using the latest firmware revision. Consult your DMA documentation for more information on updating its firmware.

4.The media vault’s media server supports the playback of the following file types:

Video: .mpg .wmv .mp4 .avi .asf .mov .vob .mpe .ts .dvr-ms .m2v .mpeg .m2p .divx .xvid .dat .m1v .m4v

Music: .mp3 .ogg .wav .lpcm .pcm .wma .mp2 .ac3 .m4a .aac .mpa .mp1 .aif

Note: Some DMAs have playback restrictions for certain types of multimedia files. Check your DMA documentation for supported and unsupported file types.

5.New multimedia files can take a considerable amount of time to show up on your DMA. The streaming process requires the media vault’s media server to scan through new multimedia files to gather information, such as artist names, song titles, video names, and so on. This process often takes a long time—especially if there are a large number of files. Once the scanning process completes, you will see the files on your DMA.

6.Reset the media streaming database. For more information, see Reset media streaming.
