Does anybody have the full list of the changes made to Sky+ by the latest upgrade. I got the upgrade last week and I've already set my on-screen icon to auto-hide. I've worked out most of it I think but a list would be useful. I've found if you hit 0 on the remote you get the channel core number entry in the bottom corner (where you would normally enter 104 for Ch4 say) but it starts with a speaker symbol. What does this do? I've tried adding know channel codes including radio channels and it just says channel unavailable.
