I've been having this problem for quite some time now. My external HP DVD840e will not load original copy protected dvd's. The drive tries to read the disc for a minute or so then stops, but when I try to access the disc or play it I get an error message saying that their is no disc in the drive. Under the drive properties it has "0" set for the region code. I've tried to change it back to region "1" with out any success. My internal dvd drive will load dvd's with out any problems since its location region code is set to "1". See attached screen shots for more details and error msg. Thanks for any help on this issue.
