I must comment again on how great this forum is to keep up to date with this sort of thing.
Many of the channels are working, but many still aren't. It does look like it's mainly sky's own channels (as James mentioned) which are sky 2/3, sky movies, a lot of the sports channels along with the discovery channels.
One of us is very happy as it looks like there won't be any sport and a lot of Grays Anatomy / Desperate Houswives – doh!
Thank you all for your help on this.
