burned DVD won't play

[David Grotell]

I'm trying to copy a homemade DVD, and after I make a copy, it comes up on the desktop with a name, but it won't play. The information from the films is in there when I click on it, but it won't cause the DVD player to open, and when I try to open it, it says "can't read media." I made the copy in the simplest way possible: opened up my old DVD, dragged the audio and video folders onto the desk top, then dragged them again into the burn window, and did the burn, at the slowest speed. Why won't it work? Did I forget something? I'm on a fairly new MacBook Pro with OS 10.4
Thanks.

I cannot proof that your manual method is not good but i fear that it does not respect the UDF format of the DVD to be playable; your one "by copy" is a simple "data" DVD

I use this method which uses a disk image as an intermediate step and which never fails on my SuperDrive:

Is this made from a commercial movie DVD?
If so, the reason it won't play is that the DVD is encrypted, and the code cannot be copied when you make an exact copy of the disc. It copies the data, but you cannot copy the key. Blame Hollywood.
