Making illegal copies of films, music, books and games 
Downloading and seeding torrents 
Using someone else's program code without license
Plagiarism (which is like breaking 9th Commandment)


Are the things listed above sinful? 

Does it depend on whether we're making money from it?
This issue is really just a sub-set of a much larger issue. See my answer on Are Christians bound to the laws of their country? for a defense of why Christians are bound to follow the laws of their countries whether or not they agree or disagree with them.

Whether or not some of the items you list would or would not fall under a biblical definition of "theft" and thus run afoul of one of the ten commandments, breaking a civil law is still something we're instructed against according to Romans 13:1. Hence breaking civil laws and ethical standards is also disobedience to God, which is sin.
