Laptop Cannot Play DVDs in DVD drive

[Un4g1v3n]

Alright. New issue!

My friend's laptop used to work perfectly fine. It used to play DVDs and all that good stuff. However, one day she had to get it repaired and they needed to reformat the computer. However, now she cannot play DVDs on the computer.

The computer reads the DVD name and disc size, etc... But no viewer can play the DVD. All viewers say that the files are missing.

Toshiba Satellite M70-SR6 (Part no. PSM71C-SR600E)

Any help is greatly appreciated.

*Tried updating all drivers, etc..

Okay, well I've been messing with this all night and now I have a new error. This is seriously frustrating me because it seems that there is no real end to this. No matter what I get error after error.

New error:

"Windows Media Player cannot play this DVD because there is a problem with digital copy protection between your DVD drive, decoder, and video card. Try installing an updated driver for your video card."

Ive downloaded codecs and encoders. I've tried updating my drivers, anything I could think of. What's going on? Any ideas?

Un4g1v3n,

Right click on My Computer and select properties now go to the Hardware tab and click the Device Manager button.
Do you see any yellow icons?

[Un4g1v3n]

Nope.

Everything is fine. There is no unkown devices, and all the categorized devices are working fine.

Have you tried a dvd player like ?

Laptops can be tricky when it comers to drivers are you sure you have the right video drivers for the onboard video?
You could use a program like to verify the onboard video make and model and that you have the right drivers.

Everest told me everything I already know. The DVD drive type is:

Matshita DVD-RAM UJ-841S

Motherboard Name:

TOSHIBA Satellite M70

MoBo ID:

<DMI>


I've WMP and InterActual DVD players. Honestly, this is a problem I've never really seen before. :S

[Un4g1v3n]

InterActual is now telling me I have a problem with the audio subsystem. I updated the sound drivers and installed the latest DirectX. Still nothing.

I get to the main menu for the DVD, but when I try to play it, I get the error listed above.

I still get the same "Digital Protection" error from WMP.

Toshiba doesn't offer recover discs to download either. Not that I've seen on the website anyhow.

Let's make sure that the drivers for the dvd drive are there.
Below are the drivers that windows installs for a dvd/cd drive.

c:\windows\system32\drivers\cdrom.sys
c:\windows\system32\drivers\lmapi.sys
c:\windows\system32\drivers\redbook.sys
c:\windows\system32\drivers\storporp.dll

Are those listed as the drivers for the dvd drive?

Is this a dvd burner also or just a dvd reader?

[Un4g1v3n]

Writer, aswell.

Also, those 4 drivers are listed under Driver Information.

Let's make sure that the drive is set to DMA.
Click Start, click Run, type devmgmt.msc, and then click OK.
Expand IDE ATA/ATAPI Controllers.
Right-click the controller that you want to configure DMA/PIO settings for, and then click Properties.
Click the Advanced Settings tab.
In the Transfer Mode box, click DMA if available.

Next make sure that you have a compatible decoder installed.
In Windows Media Player, on the Tools menu, click Options to see if the DVD tab is available. If a compatible decoder is not properly installed, the DVD tab will not be available.

Now make sure that the upper and lower filters are not the cause of the problem:
Step 1: Start Registry Editor
Click Start, click Run, type regedit, and then click OK. Registry Editor starts.
Step 2: Delete the UpperFilters registry entry
1. In Registry Editor, expand My Computer, and then expand HKEY_LOCAL_MACHINE.
2. Expand SYSTEM, and then expand CurrentControlSet.
3. Expand Control, and then expand Class.
4. Under Class, click {4D36E965-E325-11CE-BFC1-08002BE10318}.
5. In the right pane (topic area), click UpperFilters.

Note An UpperFilters.bak registry entry may also appear. To delete the UpperFilters registry entry, you must click UpperFilters and not UpperFilters.bak.
6. On the Edit menu, click Delete.
7. When you receive the following message, click Yes to confirm the deletion of the UpperFilters registry entry:
Are you sure you want to delete this value?
The UpperFilters registry entry is removed from the {4D36E965-E325-11CE-BFC1-08002BE10318} registry subkey.

Note Do not exit Registry Editor. You must have this program for the next step.
Step 3: Delete the LowerFilters registry entry
1. In Registry Editor, expand My Computer, and then expand HKEY_LOCAL_MACHINE.
2. Expand SYSTEM, and then expand CurrentControlSet.
3. Expand Control, and then expand Class.
4. Under Class, click {4D36E965-E325-11CE-BFC1-08002BE10318}.
5. In the right pane (topic area), click LowerFilters.

Note An LowerFilters.bak registry entry may also appear. To delete the LowerFilters registry entry, you must click LowerFilters and not LowerFilters.bak.
6. On the Edit menu, click Delete.
7. When you receive the following message, click Yes to confirm the deletion of the LowerFilters registry entry:
Are you sure you want to delete this value?
The LowerFilters registry entry is removed from the {4D36E965-E325-11CE-BFC1-08002BE10318} registry subkey.
8. Exit Registry Editor.
Step 4: Restart the computer
If a CD recording program no longer works after you restart the computer, you must reinstall the CD recording program.

You need to install a DVD Player like Power DVD. The laptop should have come with a DVD player program. Windows media player doesn't know what to do with a DVD.

There is no recovery disk because Toshiba Laptops usually have recovery software on a seperate Hard Drive partition. My mate has used it on hers twice, so the recovery program appears relatively stable.

As for the DVD issue, try to remember if you installed any programs near the time it went wrong - my DVD drive stopped working once when I installed Itunes, because of some unknown driver incompatability. I ended up removing Itunes (as its rubbish anyway, and MediaMonkey and VLC are far better).

Hope some of this helps. Good luck.
