There are many factors that have to be taken into consideration when ripping a DVD.
Compressing the movie if itâ€™s a DL disc.
Removing the encryption keys
They all play a part
RIPLOCK removed allows a SL pressed DVD-Video disc to read at up to 16X on the 35xx series drives
RIPLOCK removed allows a DL pressed DVD-Video disc to read at up to 7X on the 3500 and 3520 and at up to 12X on the 3530 and 3540.
To sum up. RIPLOCK removed only removes the speed restrictions on the read speed of SL and DL pressed DVD-Video discs.
