I have a new external drive DVD drive. On some dvds I get just a blank grey screen for the menu or I get large grey horizontal lines and artifacts going through the menu and the whole movie. I play the dvds in other players and they work fine, no grey lines. Below is the report.
Below is the log for the grey menu
