Get YouTube Video (improved)

--------------------------------------------------------------------------------
**** Question to Users: ****
How many of you use the various options like play with ffplay/mplayer, encode with ffmpeg/mencoder?
I'm thinking about removing those options because I'm not using it and I never tested them (the encoding options). They are there since the initial fork.

Update:
Because I got no replies on this I assume no one is using this options so I removed them.
--------------------------------------------------------------------------------

In version 1.6 I changed the localization strings of all languages a bit. I have no idea if I did it right, because I only know german and english. Feedback on this would be great.

Usage:
Right-click onto a link to a YouTube video or at the background of the YouTube site showing the video and choose action -> Download YouTube Video -> ...


Automatic Installation (may not work because of distribution specific paths):
tar xvjf youtube-servicemenu*.tar.bz2
sudo ./youtube-servicemenu*/install-kde3.sh

Or if you use KDE 4 on Fedora:
sudo ./youtube-servicemenu*/install-kde4.sh

About:
I made some modifications to the YouTube Service Menu. It didn't work for me, so I looked at the source. I added a different method to guess the video_id and I added additional parameters to the query string to download the video.

With this konqueror service menu it is possible to download a youtube video
by right clicking a link to the video and choosing "get youtube video" from the
actions menu.

version 1.8:
FIX: adapted to new youtube HTML and JavaScript.
NEW: help message for the shell script.

version 1.7:
FIX: adapted to new YouTube JavaScript.

version 1.6:
NEW: Use --format=mp4-hd to download HD version of the video (option is present in the servicemenu). This is not
available for every video (might result in a file not found error).
FIX: Fixed error message for invalid format.

version 1.5:
NEW: More video formats supported by get_yt_vido.py (flv = 320x240, flv-hq = 480x360, 3gp = 176x144, mp4 = 176x144 and mp4-hq = 480x360). However, the service menu dosen't display them all.
Droped python 2.3 support.
Internal improvements (module subproccess and htmlentitydefs are used now).
Updated translation strings (there seems to be something wrong with this?).

version 1.4:
NEW: Option to download the MP4 version which uses h264 video codec (far better video quality if the original video was in good quality and SEEKING in vlc!).
