Channel Five launched a new “catch Up” channel today – Channel 5+24.
It has meant a shuffle of some of their channel.

On Sky:

105 – Channel 5
171 – Channel 5 HD (subscription required)
174 – 5 USA
175 – Channel 5+24
176 – 5*
177 – Channel 5+1
219 – 5 USA+1

On Freesat:
105 – Channel 5
128 – Channel 5+1
129 – 5 USA
130 – 5 USA+1
131 – 5*
132 – Channel 5+24

So it looks like 5*+1 has been dropped for Channel 5+24.
