Simon,

Try these for the power control.
On:
900A 006D 0000 0001 00BF 5FA0
Off
900A 006D 0000 0001 00BF 5EA1

If they work, you should be able to figure out how to enter the other codes by hand. You may also want to have a look at the http://www.onlyoneremote.com database as I think it has the codeset as well.
