Hi Doc!
I use a single BMP image for the opening zone screen on my Beo5. I just increased the pixel size of the image. It took a few guesses to get the size exactly correct but looks good.
I've also used a single BMP image for channel slection on my Beo5 for sat. My four year old son uses the Beo5 to change to Cbeebies etc, and knows the logos rather than the channel numbers. I placed the single button with IR code in the middle of the screen and assigned the logo after resizing it. Hey presto, it now takes up most of the screen and he just presses it in the middle to work it! I then used another 'page' to do other channels!
