Anyway, the interesting question is "What constitutes a good faith attempt?"
The internet seems to be a great place, between rare CD stores or used copies. Beyond that, there is always the possibility that the publisher or creator might know. An e-mail I sent to Presto Studios asking where I can buy a CD turned into the CD in question, and some other promotional items sent to me for free. It's amazing what can happen when you show interest in something long since discontinued.
Right now, I use my share of P2P programs, but for one purpose. A VCR. I don't own one, nor will I buy a DVD burner until they settle on a standard, so for now I tend to download TV episodes I want. Right now for example, I have all of Farscape on CD, and when the DVD is released, I buy it and destroy the approiate CD. It's also been handy for catching up on shows, like Jeremiah on Showtime. I managed to catch the second episode when I subscribed to Showtime, and have now downloaded season one to be prepaired to see season two this fall.
While I don't like the crackdown actions by the RIAA and such, I can see why it's done. I see so many people now downloading stuff for free, and just expecting it to be that way. I guess many see it as corporate backlash, but unfortunatly right now, all it does is really hurt the little guys. Both on the creation side (the artists, etc) and the small stores. It seems everyone is willing to deal with crap on their computers while they download stuff, but they are unwilling to do anything to fix the problem, like wiriting their representitives, and voting with actual thought.
