Installation

Automatic (only PlayOn!X users):

cd /tmp && wget http://playon.unixstorm.org/youtube/latest-youtube-playonx.sh && sh latest-youtube-playonx.sh

If you don't have the latest RSS pack yet, you have to update Youtube item in menu.rss as well.

Manual: first extract Youtube package into /home/scripts/ directory, then add (or replace existing) following item in /home/scripts/menu.rss:

<item>
<title>Youtube</title>
<link>http://127.0.0.1:82/Youtube4/you.php</link>
<media>/home/scripts/Youtube4/images/Youtube.jpg</media>
</item>

Configuration

Automatic: use Youtube Web Configuration (open http://REALTEK-IP:82/Youtube4/web.php) to change settings. Hover over question marks to see a pop-up with more information. Recommended screen resolution for using web-interface is 1024x768 and bigger.

Manual: look inside of /home/scripts/Youtube4/settings.xml file.

Downloads

This is a correct order to determine which path is selected for downloading files:
1) Internal HDD
2) External USB1
3) External USB2
4) Youtube path

Files can be found in download/ directory. In case of problems, look into /tmp/youtube-download.log file for details.

Troubleshooting

Can't enter Youtube main menu
Make sure that lighttpd webserver is running and path to Youtube package is correct in menu.rss.

It's not possible to play video in HD quality
The list of streams is depending on formats provided by Youtube.

Can't play video error
If HTTPD value in config.inc is set to on, make sure that /tmp/www/ is writable. If it's not possible because of read-only filesystem, set HTTPD to off.

Video starts, but stops too soon
If HTTPD value in config.inc is set to off, check server.network-backend value in your lighttpd.conf file and change it to write.

Downloading FLV clip is taking forever
Most of the time download speed of MP4 format is much faster than FLV, so use MP4 whenever it's possible.

Downloading doesn't work at all
Usually this happens on non-PlayOn!X firmwares where different version of Busybox is being used. Check /tmp/youtube-download.log file for errors.
