Yet another

I'm afraid.
Although a combined sky+ and dvd recorder question I thought I'd ask in here...
As some of you will have read I'm getting sky+ tomorrow.
What I'd like to know for SURE is - do sky box office films have macrovision on them?
Now my dvd recorder has a modified firmware on it which disables macrovision (I know this works as I've copied some of MY pre recorded vhs tapes and DVD's onto dvd).
What I'd like to know is will I be able to record from the sky+ box to dvd?
p.s. how easy IS it to put a bigger hd (I was thinking 120gb) in a sky+ box?
Once again - cheers for the advice.
