No. Any DVDs can easily be copied (including Hollywood DVDs WITH copy protection) with a few programs downloaded from the internet. Besides, copy protection that is available only works if you have them replicated which is cost prohibitive for small runs.
The best copy protection is to tell (and if possible do) everyone that you will personalize each dvd with their name in the intro or something similar. This helps a little because why would dave want a dvd that says troy's dance session.

Well, Dave might prefer making a copy of Troy's disc for the cost of a blank DVD rather than paying $20 to get his own personalized copy.
I'm not sure that even the Hollywood protection schemes help much. Using nothing more than Windows Explorer you can usually drag all the files from a commercial DVD to the hard drive, then burn them to a new blank using Roxio or Nero (as long as they'll fit on a 4.7GB disc, of course). It's not particularly effective protection.
That's really odd, I've had incredible trouble trying to copy the DVDs that I burned. I finally had to resort to burning a backup disc with the UDF Data disc format. Whenever I tried to copy the files to my hard drive from a typical burn, somewhere along the process it would cancel because it said it couldn't read from the source file. I don't know what happens when I burn, but it seems to create protection on mine!
Did you create the DVD with DVDA? How large are the VOB files? I read a post where someone mentioned that if your VOB file is right at the 2GB limit, and since DVDA appears to be creating VOB files that violate the spec (they are 1 byte too large), windows won't copy the VOB file.
If I recall, on average my VOB files are right around 1 GB each. Maybe one hits the 1.2-1.5 size, but mostly they are under a GB. And yes, DVDA burns all my videos. I only use Nero to burn the UDF format for backups.
