Aside from the specifics of DVD copying. Legal issues are of great interest to me. They all share the same probable cause burden for law enforcement no matter what you are being arrested for.
To make an example using this DVD copy thing (and it could be anything from burglary to selling narcotics). If someone tells someone else that you made a copy for them, the information is useless to law enforcement, at face value, as it is "heresay".
If you copy a DVD for someone who provided the original and told you "in good faith" they owned the DVD and later law enforcement found the DVD and this person told them where they got it. The information is useless at face value assuming that making copies of your own DVDs is legal.
Even if you just made a DVD copy and sold it to someone, and later that person called law enforcement on you. The information at face value is not enough to arrest you.
In the above examples, law enforcement may be able to argue something called "reasonable belief" that you are engaged in illegal activity. With that level of proof, they may be able to nudge your rights a little to look deeper.
Now on the other hand, if law enforcement learned you committed (at different times lets say) all of the above acts. Then my friend you get to wear the silver bracelets.
The thing is, you DON'T have to be guilty to be arrested. Law enforcement needs to meet their burden. That is that they have "probable cause to believe a crime has been or is being committed." If they have that, you get ink on your fingers, and a judge gets figure out the rest.
Another point of interest (maybe) no law enforcement agent can arrest you "at all" regarding something that happened in the past. Not without a warrant which is signed by a judge by the way, so if you get arrested with a warrant ... ya gotta believe that the case against you is pretty good, or the judge wouldn't sign it. So if you see the cops coming to your house a week or so after the act ... you better start eating DVD as fast as you can!
I sure can't help much with CD / DVD knowledge so if that helped anyone ... I'm glad I was able to. It may be one of the few times I can, till I figure this burning stuff out myself!
