Are all these files needed for MBR streaming? event.xml,manifest.xml,event1.f4m,event1.m3u8?

When streaming live multiple bit rate events, are all four of these xml files necessary and in the correct location? Seems like duplicate information.

Say my event is called 'liveshow'

Event Directrory (2 files) > C:\FMSHOME\applications\livepkgr\events\_definst_\liveshow.

Event.xml

<Event>

  <EventID>liveshow</EventID>

  <Recording>

    <FragmentDuration>4000</FragmentDuration>

    <SegmentDuration>400000</SegmentDuration>

    <DiskManagementDuration>3</DiskManagementDuration>

  </Recording>

</Event>

Manifest.xml

<manifest xmlns="http://ns.adobe.com/f4m/1.0">

  <media streamId="stream1" bitrate="200" />

  <media streamId="stream2" bitrate="350" />

  <media streamId="stream3" bitrate="500" />

</manifest>

In the webroot (2 files)

liveshow.f4m

<manifest xmlns="http://ns.adobe.com/f4m/2.0">

  <baseURL>http://FMS/hds-live/livepkgr/_definst_/liveshow/</baseURL>

  <media href="stream1.f4m" bitrate="200"/>

  <media href="stream2.f4m" bitrate="350"/>

  <media href="stream3.f4m" bitrate="500"/>

</manifest>

liveshow.m3u8

#EXTM3U

#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=200000

http://FMS/hls-live/livepkgr/_definst_/liveshow/stream1.m3u8

#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=350000

http://FMS/hls-live/livepkgr/_definst_/liveshow/stream2.m3u8

#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=500000

http://FMS/hls-live/livepkgr/_definst_/liveshow/stream3.m3u8

Also why does 'Manifest.xml use '<manifest xmlns="http://ns.adobe.com/f4m/1.0">' and 'liveshow.f4m' use '<manifest xmlns="http://ns.adobe.com/f4m/2.0">' ?

Thanks for all the help!
