If the text is too small, you can put the guide into SD mode. This will cause the guide to be displayed in 4:3 with black bars on the sides, but it will also cause the text to be enlarged and spaced out.
To do so, press Menu, select Settings, select Video Settings and then select Graphics Settings and choose SD. Indicate that you have a 4:3 television. You'll notice that the guide and menus now occupy the middle of the screen instead of completely filling the screen.
not everyone has that option of graphic settings
If you do not have the Graphics Setting option, it's because you are using a QIP-6xxx set-top-box which only supports the SD guide, so you are already getting the enlarged fonts.
