tv-star.sh, a little script for managing tv.

Hi altogether!

I wanted a very small app to watch and record tv with my dvb-t stick, so I created tv-star.sh:

#!/bin/bash
#
# Befor you start, you need to edit the 2 
# variables SCANBASE and MOVIEFOLDER
#
# This is the base-file for the frequency-scan.
# Chose the one corresponding to your location.
SCANBASE="/usr/share/dvb/dvb-t/de-Schleswig-Holstein"

# Folder where the movies are stored.
# IMPORTANT: Use the full path, don't use ~ for your home!
# Example:
# MOVIEFOLDER="/home/tux/tv/"
MOVIEFOLDER=""

I am no programmer, so if you have any ideas how I can make the script better, please tell me!
