When I try to create image file from disc (WITH 2 DIFFERECT DVDS) I get message "Sorry using Read mode to create an image file from a multi-track DVD-Rom disc is not currently supported. Instead us Build mode to create a new 'clean' image based on the contents of the disc. When I change the mode to build, I get the message there is nothing to build! I'm trying to copy a disc I made from the TV. One ran without commercials for 1hr and 30 min and one was 24 min for 9 days (a study program).
