Tvheadend

Hi
I'm using epguide (http://code.google.com/p/epguide/downloads/list) to grab tv programme.
This is script to grab xmltv to TVH:
#v+
streamer tvheadend # cat /usr/bin/tv_grab_file
#!/bin/bash
dflag=
vflag=
cflag=
if (( $# < 1 ))
then
#cat ~/.xmltv/tv_grab_file.xmltv
cat /opt/tvheadend/home/.xmltv/tv_grab_file.xmltv
exit 0
fi

for arg
do
delim=""
case "$arg" in
#translate --gnu-long-options to g (short options)
--description) args="${args}-d ";;
--version) args="${args}-v ";;
--capabilities) args="${args}-c ";;
#pass through anything else
*) [[ "${arg:0:1}" == "" ]] || delim="\""
args="${args}${delim}${arg}${delim} ";;
esac
done

#Reset the positional parameters to the short options
eval set -- $args

while getopts "dvc" option
do
case $option in
d) dflag=1;;
v) vflag=1;;
c) cflag=1;;
\?) printf "unknown option: -%s\n" $OPTARG
printf "Usage: %s: [--description] [--version] [--capabilities] \n" $(basename $0)
exit 2
;;
esac >&2
done

if [ "$dflag" ]
then
printf "Graber pliku xmltv ~/.xmltv/tv_grab_file.xmltv file\n"
fi
if [ "$vflag" ]
then
printf "0.1\n"
fi
if [ "$cflag" ]
then
printf "baseline\n"
fi

exit 0
#v+

when i enable it in tvh configuration as internal graber i have "empty" program.

file /opt/tvheadend/home/.xmltv/tv_grab_file contains full xmltv program.

why grabber doesn't see any channel?
