Newbie question: If you don't consider the label, is there a simple way to tell the difference between a commercially pressed DVD and a burned DVD-R? By looking at the "grooves"? By using a computer program to check?

I tried dvdidentifier,but everything was grayed out when I clicked Identify with the original dvd.
Thank you, saugmon, I can now see all I need to know in dvdinfopro. My problem was I live in China where new DVD movies cost less than a dollar and are released almost before the filming has been completed. In China, many copies are made to look like originals, and with such prices, there are many pressing defects. So I wanted to see whether they are selling pressed or burned DVDs here.
Sounds more like majority of those pirated discs will be actually the burned format of +/-. I've never seen one.
If it is a burned copy,dvdinfopro/dvdidentifier/nero speedtest will all tell you.
Dvdinfopro has a free version with adverts. I like the PI/PO error scanning test that is in that program. Very handy indeed.
I rather think the majority of the discs will be pressed, there being a billion Chinese, they sell millions of these DVDs, with numbers like that it would take too long to burn them, even at 16x.
