Many people don't know that if you do professional editing, or professional movie, and you distribute your stuff, and its been edited on a hacked software, you can get sued, and you're in deep shit if they find out. But I guess for editing for yourself, I bet they can't really know. If you live in Canada, you're safer too.
Get final cut pro ! There was a good download of it on demonoid before it was shut down, it was 80 gigs ... Otherwise you will have to purchase it for 800 bucks or something ? anyways final cut is awesome and if u work full time it shouldnt be much of a problem and it is worth it.
