I'd suggest downloading a number of CCF's. Go to files section and download one for each piece of kit (assuming it's listed)
You can then pick and choose the best bits out of each (remove what you don't like and then save the CCF). When done load them in altogether (you are asked whether you wish to merge or replace - so you'd merge)
If you can't find a CCF for a piece of kit (unlikely) then you can just choose a nice LOOKING one and then teach it your remote's codes (overwrite the existing IR codes)
Setting up can take a while, and for many writing CCF's has become a hobby, as we all search for that "perfect CCF" for our own needs (and the other half's requests!)
