Gen3 Themes
Gen3 aka (WD Streaming Media Player or SMP) has official supported methods for themes as well as WDLXTV theming methods.
All themes once loaded can be selected in the settings menu. This is true of both official and WDLXTV theming methods.
Official Methods for running themes.
1. Upload theme via WD Official Webend
2. Select a Downloadable theme from WD servers (4 or 5 available)
Limitations and Requirements of Official Method
1. Theme must be inside a .zip file
2. Size can not exceed 30MB
3. zipped theme must not use any compression
4. Can only have 1 theme at a time. (uploading/downloading a different theme erases the one previously installed)
5. Must have a valid meta.xml (this is actually true of any theme, regardless of method used)
6. Must be zipped at root level (ie. you can't right click on the folder to create the zip file, must zip the contents of the theme folder, not the folder itself)
WDLXTV additional Methods for running themes.
Any of the following are valid folder names for running a theme.
Theme folder can be located on any attached drive.
Also Please note, while it's hard to see on the wiki below. ALL theme folders must start with a . dot
1. .theme
This is an bit depreciated now, but can still be used to force the firmware to boot to this theme at each boot.
2. .<my-theme-name>.theme
Example: .Alaska Resurface.theme
This is a Generic Theme
3. .<my-theme-name>.theme.linksheets
Example: .Goodbye Black Mamba.theme.linksheets
General Theme with added benefit of automated linksheets scanning via linksheets.pl script
Theme Tips
Which method is best for me?
I recommend you read the Gen3 Moviesheets wiki and then decide.
Where can I find additional themes?
http://forum.wdlxtv.com/viewforum.php?f=13 (very few gen3 themes can be found here)
http://community.wd.com/t5/WD-TV-Themes/bd-p/hub_themes (most gen3 themes will be found here)
I want to create my own theme. How do I start?
Start by Downloading the stock theme. http://www.mediafire.com/download/tkmbp6zg31b3h1i/Grid-UI.2.02.32.zip
Misc
Using WDLXTV methods, you can have as many themes as you want on your thumbdrive
WDTV Hub, WDTV Gen3, WDTV Gen4 themes are for the most part compatible, with a few minor glitches
If you know the correct path, theme's can be enabled via cmd line or on WEC (reboot is required)
config_tool -c THEME_PATH=/path/to/root/of/theme
