Topfield 5800/Troubleshooting/Aspect Ratio
A "clever" feature of the Toppy is that the '0' button on the remote will cycle between various Aspect Ratios (when it's not being used to enter a channel number). This will override and update the Setting in the Main Menu. You can disable this feature by using the [Z] AspectRatio firmware patch (note that you will still be able to use the '0' button to stop TAPs loading during booting).
