The 2 HD channels you mention are only available on Sky sub cards that include the HD option. Freesat from Sky cards are very limited with respect to the channels they give you over and above the free to air ones. If I remember right only a handful of Sony channels, maybe Motors TV and not much else.

I thought you got these?
If the receiver is setup correctly with the appropriate Cam it will wake and Use any Freesat for Sky Card.
The Wake up part could take anything from a few days etc...
None of the HD channels will work on any other type of receiver apart from an Official one, and as above CH5 Hd and Sky News HD are part of the subscription base pack
CCam or Oscam will still work for the remaining Sky FTV channels if the Cam/Configs are setup correctly
just checked a card here using OScam and the current SD encrypted channel list with FSFS card
