I burned a movie and under QUALITY SETTINGS I unticked the "PERFORM DEEP ANALYSIS and COMPRESS THE VIDEO WITH HIGH QUALITY ADAPTIVE ERROR". I thought it was cool cuz the time cut down the ripping time from 1.5hrs to about 22 minutes! But, the disk is not readable towards the end. It skips, and stops on my dvd player. Do you all leave these fields checked? If so, how long does it actually take to rip the dvd? Over 1 hr? Thanx!
