I have used Digiguide for around 3 years and would be lost without it. I use Digiguide to search for programmes that I want to watch and then set them to record on my Sky+ system. Very easy to use with lots of features to help choose your programmes. You can set it up to show whatever channels you want in any order you want with your DTV suppliers channel numbers and apply colour coding to genres. Excellent search feature with all Sky Movies films up to the end of December being listed. If you have never used it, give it a try, you won't be disappointed.
