Wooshbuild is excellent, it's what I put on for friends and family as know it's problem free. If you start tinkering and getting a bit bored or interested you can get in trouble. So create a backup when you have a good setup.
Then once you have a safe safe place to go back to, muck about as much as you like.
biggest nuisance is when you have a load of timers setup but you didn't back up and then you were buggering around and so you go to your safe place - your backup only to find its rubbish because everything changed afterwards.
Setup up everything you want - I mean everything, the soaps, the sharpness, the hdmi cec controls, the resolution, then make a good backup.
Enjoy.
