Tvheadend

hi there, firts of all I am a complete linux novice, I know little or nothign about it and only playign with it. BUT I need some help to set up a busienss solution for IPTV for one channel per TV with a PI at ecah tv. I have played with XBMC openelec version and have all the add ons enebaled but still get a TV headend error. What I really need is a rom that boots the PI and starts the IPTV stream automatically. Can this be done and does such an image exist or could someone help me. I don;t mind paying a small amount for such an image .

Apoligies if I am way of message on this forum, but struggling big time.

Thanks
