You can use a program like cool edit or some other that lets to record to a wav file from the line input or digital. Actually music match jukbox will let you record directly to a mp3 but the quality may not be that great. I have done the same thing from my direct tv audio channels, it works pretty well. As for the copyright stuff, I would just like to know what is the difference of recording from the radio vs. tv vs. internet why is it "ok" to record from the radio but not from the internet?
