Thanks for your feedback. 
"how do you start tvheadend in the init script" 
After the RPM-Package installation I must start the service manually by typing the command 
# service tvheedend start
  as root . I have take the init script from a clearos package, here it is
$ cat /etc/rc.d/init.d/tvheadend 
#!/bin/bash 
# 
# tvheadend startup script 
# 
# chkconfig: 2345 99 01 
# description: Tvheadend  is a TV streaming server for Linux 
# processname: tvheadend 
# pidfile: /var/run/tvheadend.pid 
# Source function library. 
. /etc/init.d/functions 
prog="tvheadend" 
start() { 
	gprintf "Starting %s: " "$prog"	 
	daemon tvheadend -u tvheadend -f -C 
	RETVAL=$? 
	echo 
	[ $RETVAL -eq 0 ] && touch /var/lock/subsys/tvheadend 
	return $RETVAL 
} 
stop() { 
	gprintf "Stopping %s: " "$prog" 
	killproc tvheadend 
	RETVAL=$? 
	echo 
	[ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/tvheadend 
	return $RETVAL 
}	 
case "$1" in 
  start) 
  	start 
	;; 
  stop) 
  	stop 
	;; 
  restart) 
  	stop 
	start 
	;; 
  status) 
	status tvheadend 
	;; 
  condrestart) 
  	[ -f /var/lock/subsys/tvheadend ] && $0 restart || : 
	;; 
  *) 
	gprintf "Usage: %s {start|stop|status|restart|condrestart}\n" "$0" 
	exit 1

"What options do you start with? using what user?"
If I start tvheadend with my user over the webintrerface "http:localhost:9981" there comes a login dialog but I have no login data (Username/password) so I start tvheadend with the option -C. By the way the permissions from the .hts directory and all subdirectories are 700? Are this permissions correct? 
$ ls -lF ~/.hts/tvheadend/ 
total 4 
drwx------ 2 mado mado 4096 2011-10-04 07:55 accesscontrol/ 
[mado@localhost ~]$ ls -l ~/.hts/
