I agree with Mentalcase, there's no problem.
I think people are way more sensitive about this "copyright" thing than they should.
As long as you do not copy someone else's work and try to make money out of it, (someone would add:

and as long as you don't get caught while doing it

) there's nothing illegal really.
In theory, it's even illegal to copy a video-tape, a CD-rom, a DVD, coz you'll have to prove that it's for your personal use only.
Blah blah blah..
