FULL PROBLEM DESCRIPTION
------------------------            
The ipplay program, which runs multicast streams, consumes
significant amounts of cpu while the stream is playing.
Once the stream has started, ipplay should be idle and
consume very little cpu.  This affects the overall
capacity of the VideoCharger server, and can degrade
other video-on-demand streams.

FILESETS:   avs.sysmgt.multicast.rte 2.0.0.5

SUPERSEDED PTFS:
----------------
IY15263 multicast fails unpredictably - bad parameters

Multicast (ipplay) can fail with bad parameter return codes
from the control server.  This happens randomly and
unpredictably due to uninitialized variables.

IY03301 allow users to loop multicast Quicktime movies

Users can specify the loop number greater than 1
in the add multicast events web page to have the videos
streaming multiple times.

To receive the looped video/audio for multicast Quicktime
videos, users should hit the pause button and then hit the
play button.

IY02816 Multicast QuickTime 4

Added support for multicasting QuickTime 4 videos

IX89003 Multicast problems

(1) Once a multicast job has started the VideoCharger
administrator is unable to delete it.
(2) If the spool file associated with a multicast job
is > 128 bytes in length, the spool file may not be
deleted when the multicast job finishes.


INSTALLATION INSTRUCTIONS 
--------------------------
(1) Download the file "avs.sysmgt.multicast.rte_2.0.0.5.bff"
in binary mode into an empty directory on your VideoCharger server.

(2) Logon as user 'root'.  Stop the VideoCharger Server by
using the command "stopsrc -cg vs".  Type the command 
"lssrc -g vs" to verify that all the processes have stopped.

(3)Apply the update using the command "smitty update_all".
For "INPUT device / directory for software" specify the 
directory in which you saved the .bff file.
        
(4) On the "Update Currently Installed Software to Latest Level" panel,
press the 'enter' key to start the installation program.    

(5) After installation has completed successfully restart the VideoCharger
server by using the command "startsrc -g vs" at the command prompt.
