How to make a theme:

Copy the standart theme to an new directory. Then rename the standard.theme
file in your new directory, to the name of your new theme.

Now you have an own theme ;-), all you have to do now is the change the images, 
their positions on the screen, the fonts, etc...

Edit the <new theme>.theme file:

You'll find seven section:
Theme, NormalTV, NoramlRadio, ReplayNormal, ReplayDVD, ReplayMP3 and Menu.

In Theme you can give your theme an name, and set the path to your directory.
(this is improtent to find your images ;-)

The other sections controls the behavior how the display look i.e. when replay an dvd,
or you hearing an radio programm.

In each section you can use Items to create your own looking. You can use an item so
often you need it (in the most cases you wont need this). The items are display in the
order you use here. So fist take a background item, and last a message item.

For a list of the items look in standard.theme, i thing all items are used their... 

!!! At the moment not all parameters of an item works, i.e. if you use an Image Item
with the parameter widht=200, height=100, later the image will be scalled to this size,
but not at the moment.!!!
