Copyright protected material should not be available for free on YouTube. Moreover, the software I used for it was purchased legally, and not through some doubtful sites.
The movies are older than 50 years, and therefore should be out of copyright protection, anyway.
Download and copying for private use is allowed, and I am not intending to start a business. You are indeed allowd to burn 4 copies of each CD, DVD for private use without violating any laws. You are only not allowed to sell them or give them to other people.
