Well the nice men came to install my digitatl upgrade on Monday - I live in a Ex C&W area - and they only had the D1000T boxes and they knew as much about cable boxes as my nan !!
I am currently waiting to find out from the operations manager if the D14001N boxes can actually be used in C&W areas - the cabling might be different I am told :o) - so as soon as I know I'll let you all know.

However I might have to lump having to pay for my phone line rental and get Sky digital as this is starting to F**k me off ever so slightly
