Tvheadend

Hi guys

I am having some issues in connecting my tvheadend to my plex server.

1- i can download the M3U list from here http://IP ADDRESS:9981/playlist/channels

2- http://IP Address:9981/stream/channelid/181318643?ticket=970317511645F225FFB5C8DC8221206651049E08&profile=pass

it works on the Plex server with IPTV.bundle directly on my raspberryPi using the licence mpeg2 key on my raspberry flash, it works without transcoding on the plex or tvheadend machine.

My issue is, when i close the channel and go back to play it again it gives me an error, as if the tvheadend pass had expired,
also when i connect a 2nd user on the Plex server to play the same channel it blocks it gives an error..

i am wondering if there is a way of hooking this up directly without requesting a user or password, btw i am starting the tvheadend with "tvheadend -C"

Also i have setup the etc/init.d script and update rc.defaults

but tvheadend does not init on reboot, i am using ubuntu-server x64 14.04lts
