Channel name display...

Is there any way of turnning off the channel name in the display?? or changeing it to display the channel number instead?? or being able to turn box off but still record (dreambox does this) This would save me time of having to rename channels that have an adult content to stop visitors asking questions

regards

Paul

Using nlb image and tried that but display shows channel name then flashes time then repeats itself very quickly, may have to try other image to see if this works correctly

thanks
