If the DVD is playing erratically
Dirt or smudges can cause a disc to skip. Clean the disc with a soft cloth. If the disc is
badly scratched, it will have to be replaced.
If a DVD movie stops playing in the middle
The DVD may be double-sided. Open the DVD tray and read the text near the center
hole of the disc. If it says Side A, flip the disc over, close the tray, and then press the
Play button to continue playing the movie.
You may have accidentally paused the DVD movie. Press the Play button to resume
playing the movie.
If you get a Region Code error when playing a DVD movie
DVDs may include regional codes that are embedded into the disc data. These codes
prevent DVD movies from being played in regions of the world that are different from
where they are sold. If you get a Region Code error, you are trying to play a DVD that
is for a different region. Make sure you play a DVD designed for your region.
If you get a "System Error: Unable to read drive" message when running a CD program
or a movie on the DVD drive
For a single-sided CD or DVD, make sure the disc is placed into the drive with the label
facing up.
Make sure the DVD or CD is clean.
Wait 5 to 10 seconds after closing the DVD tray to give the computer sufficient time to
recognize the CD or DVD.
Restart the system:
1. Remove the CD or DVD.
2. Click Start, Shut Down, Restart.
3. Click OK.
If the DVD movie doesn't fill the screen
On a double-sided DVD, each side may have a different format (standard or
widescreen). In the widescreen format, black bands appear at the top and bottom of
the screen. To view the standard format, flip the disc over and play the other side.
You may also want to test the DVD drive with diagnostics. See "Testing Hardware
Operation."
