That is total BS. Look at the part about lowering the speed of the CD-ROM drive. CD-ROM speed and DVD-ROM speed are NOT the same!!! A 1x DVD-ROM drive is the equivalent of an 8x CD-ROM drive. If a movie really needs at least 4x DVD-ROM too play smoothly, it will be equivalent to a 32x CD-ROM drive speed. So why the hell do you need to lower it? Besides, simply turing a screw to change the characteristic of the optic is even a bigger BS!!!
