[to mike] как писать с ТВ-Тюнера

Вот мой скрипт которым пишу:

#!/bin/bash

# usage: recordtv.sh [norm] [chanel] [time] [dir]
# norm - TV Standart, eg: PAL, SECAM
# chanel - chanel to record, eg: R2(NTV), SR7(Ren TV)
# time - length of capturing in seconds
# dir - where to store .avi file

# default to "SPORT"
NORM=SECAM
CHANEL=R10
TIME=10
DIR=/mnt/share2/tmp

[ -z $1 ] || NORM=$1
[ -z $2 ] || CHANEL=$2
[ -z $3 ] || TIME=$3
[ -z $4 ] || DIR=$4

# show info :)
echo " ---- summary ----"
echo " * NORM = $NORM"
echo " * CHANEL = $CHANEL"
echo " * TIME = $TIME"
echo " * DIR = $DIR"
echo " ---- ------- ----"

# toggle capturing
echo " * toggle capturing on line in"
/usr/bin/amixer -c 0 sset Line,0 90%,90% cap > /dev/null 2>&1

TFILE=${DIR}/temp_${CHANEL}-`date +%d.%m.%y`.avi
OFILE=${DIR}/${CHANEL}-`date +%d.%m.%y`.avi

# Capturing.........................
echo " * start capturing"
/usr/bin/mencoder -aspect 4:3 tv://${CHANEL} -tv \

# Reencode
