you can add a colordiffuse code like this
<colordiffuse>code</colordiffuse>
this would have to be in the background picture look for it im sure that its in the myvideonav.xml
if you want it in filemode myvideo.xml
maybe in the top area of the xml file you will see background
add this code to the that has the width 1280 and height 720
you maybe want to find a dim color like black
so you try 10ffffff and change the 1 to 2 and then 3 see what it gives you i always use the glass clear code which is 60ffffff this gives you like a glass see through when you see transparnecy skins.
okay about the up and down and left and right, okay you need to find <onright>
or ondown the way you want to fix this,
so heres an example
in filemodeviews.xml depends on the skin but 50 is inside there, but since your using the showcase you need to go inside showcase.xml and change this both the ids are inside and also the view change name
view list
you got the left menu so its <onleft>
the right scroll <onright>
<ondown>
<onup>
so on up and down are 50 which is the list default number if you dont have 50 it wont work you may see alot of errors happen somethings the view ownt work even where you want to enter programs,music and so on.
say onleft is 60
on right is 9000
which this is how most of the skins have theses ids
you want to change the <onleft> to the number you want the way you want it, this means you wil have to change the number else where, on scroll or on the left view menu.
in that same area of you will see something like this
<includes>
<include name="CommonRootView">
<control type="group">
<visible>Control.IsVisible(50)</visible>
<include>VisibleFadeEffect</include>
<control type="list" id="50">
<posx>70</posx>
<posy>78</posy>
<width>690</width>
<height>561</height>
<onleft>2</onleft>
<onright>60</onright>
<onup>50</onup>
<ondown>50</ondown>
<viewtype label="535 <--- CHANGE ">list</viewtype> here is where you want to change it the number on the left to the name you want or add since its not appearing
<pagecontrol>60</pagecontrol>
<scrolltime>200</scrolltime>
<visible>Window.IsActive(Programs)</visible>
<itemlayout height="40" width="580">
<control type="image">
<posx>0</posx>
<posy>0</posy>
<width>690</width>
<height>41</height>
<texture border="0,2,0,2">MenuItemNF.png</texture>
</control>
well still need to sort the up/down thing with tje addon shortcuts
