6. Configure the following settings as required:

   Setting	Description
   Decryption Key	For playback of encrypted streams, enter the key provided by your administrator (see ‘Playing Playing an Encrypted Zixi Stream)
   Zixi Log Mode	This integer value sets the log entry level mode for Zixi stream messages. Available Options are : Disabled (-1) , Debug (0 or 1) , Info (2) , Warning (3) , Error (4) and Fatal (5). Note: Set only as disable unless debugging. Additional disk writes can effect memory and performance
   Max Latency [ms]	The maximum latency in milliseconds of the Zixi stream over your local connection between the source Zixi Broadcaster and the VLC player.  Increasing latency will add additional buffer space to compensate for network burst loss.
   Player Cache [ms]	The length, in milliseconds, of the VLC player cache. Using skip controls may cause the player to re-buffer
   Automatically Detect Open Ports	The VLC Plugin will auto-detect default or common open ports at the Zixi Broadcaster Non-default source ports can be specified explicitly in the playback URL (supplied by you your administrator).
   Drop Frames With Missing Data	In the case of data loss, when this potion option is turned on, any partial frames are removed by the Zixi Plug-In prior to forwarding to the player. This option can improve VLC stability.
   Fixed Latency	‘On’ is recommended. Uses Max Latency specified when off, dynamically increases to Max Latency when on
   Allow Latency to Decrease	‘Off’ is recommended. Can dynamically lower latency when ‘On’ but may re-buffer if an increase is needed
   FEC Overhead [%] and FEC Blocksize [ms]	Do *not* alter. FEC settings are set automatically. These entries will be removed in future versions.

7. Once you have updated the preferences, click Save and close the VLC player. Restart VLC for your changes to take effect.
