I have a Sony DRU-710A burner with the latest BYX4 firmware in my PC, and I use it often to watch rental movies, since I have a killer sound system. The other day my wife rented a DVD movie that had just been released and she was the first to get it from the store. The DVD looked strange as it had no labels on it and it was hardly obvious which side was up as they both looked the same.
When I put it in my Sony drive it saw no disk and the drive just sat there grinding until it eventually timed out. Once I was able to open the disk in explorer but the contents was blank. I even moved the drive to my backup computer with the same results.
I put it in my cheapo DVD player and it worked fine. It also worked fine in my Liteon DVD recorder. Any other DVD I have reads fine in my Sony recorder except that one.
Is there some new protection scheme on new releases like this one that will not work in a PC installed DVD recorder?
