HP and Compaq Desktop PCs - Resolving DVD and Blu-ray Movie Problems (Windows 7)
This document applies to HP and Compaq Desktop computers with Windows 7.
This document is intended to fix problems that can happen when playing DVD or Blu-ray movies on a computer. First, test the drive to make sure the drive can read the file structure of a DVD or Blu-ray disc. Then, if the drive can properly read a disc, use one of the other sections that best fits the situation. If you cannot find a section that fits your situation, try reinstalling the DVD or Blu-ray software to see if the problem resolves.
The movie skips, temporarily freezes, or the playback is not smooth
Use each of the following steps, using the order given and playing a movie after performing each step, until the playback problem is resolved:
Step 1: Cleaning the movie disc
CAUTION: Do not change any jumper setting while the computer is on. Damage to the motherboard can result.
A dirty or scratched disc surface is the main reason that a movie can skip when played on a computer. Because the reading area on a disc is much smaller, DVD and Blu-ray movies are much more susceptible to skipping and playback problems than CDs. Skipping is much more likely to happen with movies that have been handled frequently, like those from a movie rental store.
To fix playback problems, clean the disc. Clean discs with filtered water and a lint-free cloth. Wipe from the center of the disc to the outer edge. If cleaning does not work, buy a CD/DVD repair kit available at electronics stores.
If cleaning the disc does not work and all discs play erratically, continue to the next step. If one or just a few movies have problems, the discs may be bad. Data on discs can degrade over time.
To increase the life of DVD or Blu-rays discs:
Step 2: Logging off the Internet while playing movies
Software programs can access the Internet or network while a movie plays. This can disrupt the movie. Disconnect from the Internet before playing a movie. If you are not connected to the Internet while playing movies and movies still skip, continue to the next step.
Step 3: Virus scans
Do not watch movies when the computer is performing a routine system scan for viruses. Instead, change the virus scan time to a time that does not interfere with your viewing. Or, if you disconnect from the Internet, disable your security software temporarily. Be sure to re-enable it when you are done watching the movie.
Step 4: Turning off extra peripherals (connected devices)
Disconnecting non-essential devices that are connected to the computer can free up valuable system resources and can result in better movie performance. Turn off printers, multifunction devices (or all-in-ones), and scanners, and unplug cameras, thumb drives, and portable music devices. If this does not help, go to the next step.
Step 5: Making sure that your DVD or Blu-ray drive and player software have the latest updates
Some models of DVD or Blu-ray drives show improved video playback after upgrading the drive firmware. The latest DVD or Blu-ray player software for your computer may contain updates that address playback performance problems. Use the HP Support and Drivers site to find and install DVD or Blu-ray drive firmware updates or player software updates. For more information, refer to Obtaining Software and Drivers .
Copy of a DVD or Blu-ray movie do not play
The data stored on most DVD or Blu-ray movies is encrypted and does not allow a playable movie to be copied. Making a normal disc copy of a commercial movie produces a disc that cannot be played - this is normal.
Unprotected DVD or Blu-ray movies, such as home videos, can be copied and played.
Testing the drive to see if it can read files on the DVD or Blu-ray movie disc
If the drive cannot read the files stored on any DVD or any Blu-ray movie discs, then you know that you need to troubleshoot the CD/DVD drive and not troubleshoot the discs and movie player software. Do the following to make sure your drive is capable of reading the file structure of a disc.
A specific movie title does not play
Reasons why a specific movie title will not play and what you can do:
Unable to view Blu-ray movies
Before you can watch high-definition Blu-ray movies, all of the components in the system must meet the following requirements.
Once all of these components are connected and turned on, you should adjust the display resolution on the computer to match the best possible HDTV resolution on your display device - preferably 1080p or 1920x1080. If your TV or monitor is not compatible with HDCP, then you must use a lower display setting of 480p or less.
Unable to view 3D Blu-ray movies
Before you can watch Blu-ray movies in 3D, make sure that your computer meets the following specifications and that you have the correct hardware and software.
Error: DVD decoder not found
A decoder is software that tells Windows how to put the movie image back together from the DVD files for playback. A DVD decoder not found error occurs when the decoder is not installed or not properly registered with Windows. In the United States and many other countries, DVD decoders are not free and are not legally available for free download from the Internet. The only ways to legally fix this error are to reinstall the DVD software or purchase new DVD player software.
Resolving region errors
A region error opens after inserting a movie disc into the drive. The movie cannot be played.
NOTE: The following information applies to region-1 DVDs. Depending on country/region, laws and drive behaviors may differ.
Region errors occur when the DVD or Blu-ray movie does not match the country/region in which it was intended to be sold. The drive is matched to the region it was sold in. If a movie from a different country/region is placed in the drive, a message appears and the software may not let the movie play.
The following map shows the regions as defined by the BDA .
Commercial DVD or Blu-ray movie discs contain a region code. For example, if you play a DVD disc from Region 1, and the DVD player is set to Region 2, a dialog box displays stating,. This dialog box displays the region for the inserted movie disc and the current player region, along with a list of new player regions and countries available to select. At this time you can elect to change the region.
Most disc players play up to three non-region titles before they stop playing non-region titles. When a new region is selected, a warning appears, stating the number of region changes remaining before the change is written. This is designed to prevent illegal selling of software titles between regions. Use compatible DVD or Blu-ray movies for the region you are in or replace the drive with one from the same region where the movies are purchased.
If you live in a region other than what the drive is set to, you can change the drive to match the region in which you live. For example: If a computer is purchased in the United States (part of Region 1) and is then moved to the Netherlands (Region 2), The drive region setting should be changed to match the new region. Changing the drive region setting can be done a limited number of times. To change the drive region setting, do the following steps.

Unable to view movies in Windows Media Player
When trying to view a DVD or Blu-ray movie in Windows Media Player, an error message opens stating that Windows Media Player cannot play the move because a compatible decoder is not installed in your computer.
Windows Media Player cannot play DVD movies unless a compatible decoder is installed. To play DVDs, use the DVD player that comes with your HP or Compaq desktop computer. Insert a DVD movie and select the DVD player from the AutoPlay window.
Using the Windows Media Player troubleshooter
Windows 7 includes a troubleshooter that checks for problems playing DVDs in Windows Media Player. Follow these steps to use the troubleshooter to check for problems:
Low sound when playing a movie
The sound level drops when watching a movie or listening to AC3 audio in Windows Media Player (WMP) or Windows Media Center (WMC). The sound levels are normal when listening to sound from other sources, such as games and music software.
When Windows Media Player or Windows Media Center process the AC3 sound format from a movie, sound volume is lowered. To work around this, you can view the movie in another software application (such as HP MediaSmart). If the movie contains several audio tracks, selecting stereo (not 5.1) might also work.
NOTE: There are AC3 codec tools available from the Internet that can adjust the audio gain in the AC3 codec. But be aware that If you decide to use software to adjust the AC3 sound levels, you risk damaging your speakers and audio hardware.
Using the Playing Audio troubleshooter
Windows 7 includes a troubleshooter that checks for problems playing sound. Follow these steps to use the Playing Audio troubleshooter to check for problems:
Reinstalling movie player software
Reinstalling the DVD or Blu-ray player software can resolve a variety of problems, including missing file messages, encoder not found messages, and errors involving device library (.dll) files. Use Recovery Manager to reinstall the DVD or Blu-ray player that came with your computer. For more information, see Using Recovery Manager to Restore Software and Drivers in Windows 7 .
