yes this can be done but you need to do a bit of editing yourself, this was posted on here either last week or the week before cant remember who posted it but kudos to him/her.
Basically you can change the color shown to a background image that is already in the apk itself , in the above example I used the already included black_bg.png and changed the image to a navy blue sort of colored image , there are a number of files to go through (listed below) open each file and look for for the background line it will looks something like this :-
android:background="FF000000"
change it to something like this:-
android:background="@drawable/black_bg" like in the example below
here is a list posted on the forums earlier of the locations you need to check and change after you have changed the black_bg.png
Change android:background="#exacolor" to android:background="@drawable/yourimage"
The image has to be in the drawable folder
res/layout-22/activity_channel_list.xml
res/layout-22/activity_play_stream_epg.xml
res/layout/activity_categories.xml
res/layout/actitity_channel_list.xml
res/layout/activity_load_last_live_t_v.xml
res/layout/activity_epg_xmltvn.xml
res/layout/activity_multiscreen_exo.xml
hope this help it helped me to sort it
