I own an acer aspire 5920 laptop running windows 7. the problem i have is that dvds arent recognised in the drive and wont play. CD's are fine and the settings in control panel are for dvds to play automatically in media player. this only happened recently and i dont know how to solve it can anyone help.

You could try a cleaning disc first but it sounds as if one of the lasers have gone. One suggestion for a replacement drive Click Here

Several possibilities DVD laser gone or Laser alignment electrics failed, both mean a new dvd player required.

Bad contact / cable in laptop - try removing and refitting the player to remake the contacts.

Lack of codecs to play the DVD try downloading the Klite codec pack

Problems in Device Manager - try uninstalling and reinstalling the DVD player or if it gives an error code there then

No CD/DVD or CD-ROM access is missing error Code 19, Code 31, Code 32, Code 39, or Code 41 Try this if the optical drives are not appearing in My Computer or Device Manager. (This is sometimes caused by the removal of Roxio or other writing software.) Download and save this file to your hard drive. Navigate to where you saved it and double click the file to extract the contents. Locate the EXE file you extracted and double click it. A confirmation dialog will appear when the script is done. You may need to reboot for the change to take effect. This utility is only intended for Windows® XP, but also appears to work for Vista and Windows 7. You may need Administrator level access to use this utility. If you do not have Administrator level access, the program will say it is finished, but will not have made any changes.

Similar fixes works for vista or XP

or manual fix Run regedit and navigate to registry key HKEYLOCALMACHINE\SYSTEM\CurrentControlSet\Control\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}. Highlight it and in the right pane, find the Upperfilters and Lowerfilters values. Highlight each one in turn, right click and delete them. Close regedit and restart the computer. If in doubt make a restore point before making changes.

thanks for that reply but i dont see that the drive is faulty because it recognises and plays audio cds without a problem

Can either use a separate laser for DVDs or move the single laser to a different position to read DVDs

any further help on this matter if anyone has ideas please. I cant even run a dvd cleaning disc as that isnt recognised. Ive tried taking it out and putting back and reinstalling software to no avail

I suspect the Fruitbat /\0/\ has already given the answer ie new drive required. Is it under warranty? Try calling Acer Acer Support

Something to try and nothing to loose, right click My Computer/Properties/Hardware/Device Manager Uninstall the CD/DVD drive then reboot your PC and dry a DVD

PS Failing that if its a windows Problem, Try using System Restore to a Date when it worked these are in BOLD print
