Theres probably nothing to do but wish for ntl to spontaniously replace all their old boxes
But it's quite annoying that it repsonses slowly sometimes. Example:
you press TV for the now and next bar
Nothing happens
you press again, again and again
3 secs later the boxes flashes on and off and on and off.
It's very annoying when entering three digit channel numbers. I always end up pressing one number twice because it responds slowly.
This isn't all the time - but often. It's being used for broadband if that makes any difference.
It's an original Cable & Wireless STB probably the 1000 model
