The Electronic Frontier Foundation has an excellent list of "Frequently Awkward Questions for the Entertainment Industry".
An example for the RIAA is:
"DRM has clearly failed to stop songs from getting on file sharing
networks, but it does prevent me from moving lawfully purchased music onto my iPod and other portable devices. Unlike the major record labels, many popular indie labels offer mp3 downloads through sites like eMusic. Why won't you let fans purchase mp3s as well?"
An example for the MPAA is:
"Why are there region-code restrictions on DVDs? How does this prevent copyright infringement? Is it illegal for me to buy or and use a region-free DVD player, or to modify a DVD player to be region-free?"
