My hp dv900 recognizes and plays a movie dvd, but windows media player won't rip it.it tells me to insert a blank cd

One of the advantages of owning an HP Pavilion includes playing your favorite DVDs conveniently at home or anywhere with your HP Pavilion laptop or notebook.
Whether you have Windows 7 or Windows Vista, your HP Pavilion may experience problems playing your DVDs.
For example, sometimes you may have a DVD movie skip while playing, which can happen frequently with a lot of DVD handling, such as with rental DVDs.
Perhaps your DVD player does not recognize the DVD and rejects it.
When you troubleshoot your HP Pavilion DVD player, you become more acquainted with your HP Pavilion, plus you can get back to movie-watching sooner.
Clean the DVD if you notice any skipping while playing or if the DVD stops.
You can clean the DVD by wiping it from the center to the edge using a lint-free cloth and filtered water.
Avoid watching DVD movies while you have a virus system scan operating on your computer system.
Reschedule the virus scan to another time or disconnect the scan temporarily and then reconnect the scan when you have finished watching your movie.

Disconnect from the Internet while watching movies.
Other programs on your HP computer can access the Internet and disrupt the movie as you watch.
Turn off your printer, scanners and other external devices connected to your HP Pavilion while you watch movies.
This allows your computer to concentrate its resources on your DVD player.
Install the latest DVD player updates from the HP Support and Drivers website for the best DVD performance.
Test the DVD Drive
Insert the DVD into the HP Pavilion DVD drive. Close any window that opens automatically.
Click "Start" and then "Computer."
Right-click on the DVD player icon and then choose "Explore."
Check to make certain you placed the DVD into a DVD drive.
If the HP Pavilion DVD drive ejects the disc or prompts you to insert a disc, it does not recognize the DVD.
You can also try inserting another DVD disc. If you do not see folders appear, such as VIDEO_TS and AUDIO_TX, you may have a defective disc, or the DVD may not be compatible with your DVD drive, such as a Blu-ray disc.
Try a different DVD movie.
Insert a regular CD into the DVD drive to see whether HP can read it, after you have tried playing several DVDs.
If the drive can read the CD, it may not be the DVD drive.
Have the internal ribbon cable replaced if the drive cannot read the CD, or have the DVD drive replaced if a new cable does not help.
Reinstall DVD Software Windows 7
Click "Start," "All Programs," "Recovery Manager," and then "Recovery Manager." Click "Continue" if prompted by Windows 7. This will bring up the HP Recovery Manager window.
Click "Software Program Reinstallation" and then "Next."
This will bring up the HP Software Program Reinstallation window, which allows you to reinstall the programs that originally came with your HP Pavilion.
Click "Next" and then follow the instructions provided.
Restart your computer after the driver installation.
Select "Next" and follow the directions provided to recover and reinstall the DVD player software that came with your HP Pavilion.
Reinstall DVD Software Windows Vista
Click "Start," "All Programs," "PC Help and Tools" and then "Recovery Manager." This will bring up an HP window called Recovery Manager to help you recover HP Pavilion drivers and programs.
Click "Next" and then select "Yes" or "No" when prompted to perform a program recovery.
Select "Next" and follow the directions provided to recover and reinstall the DVD player software that came with your HP Pavilion.
HP Pavilion PC Laptop Blue Ray not working
Blu-ray disc technology continues to improve and advance, so simply having a Blu-ray player in your computer doesn't guarantee that all discs will play immediately.
The Hewlett Packard DV7 Entertainment Notebook has a Blu-ray player, but as the technology advances you have to keep the software and firmware on the system up-to-date to ensure compatibility.

Reboot your Pavilion notebook.
A minor miscommunication between the disc drive and Windows Vista or 7 may lead to a disc read error.
Rebooting clears your system's memory and forces Windows to reload all of your device drivers, which may resolve a minor kink.
Play your Blu-ray disc to see if the problem is solved.
Open QuickPlay and update it.
Double-click the "Update" button to open "Updates and Enhancements."
Double-click "Get the latest QuickPlay updates."
Select "Download now!" on the next screen and wait while the file downloads and installs.
Close and reopen QuickPlay and insert the Blu-ray disc again.

Update MediaStart regularly.
This program tracks updates for your Blu-ray player's firmware, the software coded onto the device to tell it what kinds of discs it can read.
Open MediaStart and select "Update your MediaStart." Updates are only listed when available, so if you don't see an update, check back in a few weeks.
Each update for the Blu-ray player enables you to play more recent discs, since some interactive features may not be compatible with older software.
Restart after each update.

Update your software on a disc-by-disc basis.
According to HP, some Blu-ray discs have special content protection and require new codes for you to play the movie.
These codes or disc-specific updates are stored on the disc.
If you are prompted to download a free update after inserting a disc, follow the prompts to do so. The updates will be different for each disc.

Check to make sure your player will play regular content if you continue to have issues with Blu-ray discs. It may be that the error is related to the drive, not the type of media.
Try a CD-ROM or a standard DVD to see if the disc responds.
If not, contact HP for a replacement or for drive-related troubleshooting.

The light is there to tell you that the unit has recognized the disk and is waiting you command. Just open My computer, right click on the disk icon and select play. If it says that it doesn't know how to do it it means that you need a media player capable of playing it. In that case Install VLC

and play the movie with it.

You Need a movie playing software to be able to play movie on your system. You have to download and install a movie software to play your movie. Also note the format on which the Movie is made and download the player that can play that format.

Best of Lucks.

Hello
Are you using windows media player or roxio or any burning software?
You will need burning software for blank disc to be recognized.

Hope this helps.

go to safemode and try reading CDs in safemode. If your burner still can't read CDs then it's most likely bad. You could get an external usb burner.

you may not install the proper drivers of your burner, install it again and use some other burner application like nero cd burner etc.

I have a Pioneer DVDRW DVR-K16, in a sony dv81114Notebook. Running Windows XP. It cannot play dvd's and cd's, It will recognize blank CD-R's but when I insert a DVD-R it say's no disc installed. I have firmware version 1.15.

Are you sure E: is the cd/dvd burner?

Can you put a cd with music or a dvd movie in there and get it to play it?

well u need to check for the latest software available for your dvd drive try and find the latest software on net according to your company,and check wether the software ur using comaptible with ur windows

When you say it won?t read are you trying to play commercial DVD movies or read DVD data disks? If you're trying to play movies then you need a couple of things the first being some type of player program. Real player works as does Windows media player but usually DVD drives come with a striped down version of PowerDVD or WinDVD. If you in fact have a player installed and when a DVD is inserted in your drive it doesn't play it may not be configured to automatically play DVDs. Try opening your player program and trying to manually play your DVD. Let us know if you have any success or if you need more assisted. If you do let us know what player program and operating system you have and any error messages that may appear.
