Mounting Position
You can operate your PX-750 drive in either a horizontal or a vertical
position.
Playing DVDs
To play a digital video disc, insert the DVD as you would any other
disc. The drive plays both single layer and double layer discs.
The first time : A code on each DVD allows it to be played only on
players designed for a certain regional area, such as North America,
Europe, etc. When the drive ships from the factory there is no region
code set. The first time a DVD that has a region setting is inserted into
the drive, the drive is automatically set to that region code.
If you later insert a DVD with a different region code, you are prompted
to either accept changing the new region code or not. If you don’t accept
the change, then that DVD will not play. If you do accept the change,
then the region code setting is changed. But remember: you can change
the drive’s region code only 5 times. After that, you can’t change it any
more.
