Hi, Just use the xml here to replace your file (keep the original as you will need to revert back to it) reboot smp then it will tell you where each image is being saved to… you know what I mean when you try it!!!
I hope this might work and be some help to anyone who wants to create a theme with the grid home screen. I downloaded wdtv_gpl_code_package_1.00.39 and found the meta.xml for both the grid and mochi themes. In the meta.xml there is <ui_style>. <ui_style>tabs</ui_style> in the mochi meta.xml and <ui_style>grid</ui_style> in the grid meta.xml. Below is the meta.xml for the grid theme.
Below is the theme_builtin folder. What’s included are two folders grid and mochi each contains the meta.xml and a screenshot folder. The images and xml’s are located in the resource folder.
