If you can remember a time when it worked, the simplest solution may be to use system restore to a time when you think everything worked. If that doesn't do it, go to Control Panel, open device manager, and and check for any yellow checks for your CD/DVD ROM drives, and your sound, video and game controllers. If there are none, your system is go. Also go to your audio manager on control panel, and set it up for whatever speaker configuration you have. But most likely, your CD/DVD burning program may be corrupted. Remarkably, the drives don't work unless you have a functioning non-microsoft CD/DVD burning program. They don't need drivers. Find out what program you have by downloading Belarc Advisor, a free program which not only tells you everything in your computer, with model numbers for hardware and all of your software (with their unique codes), and will also inform you if you are missing any needed Windows updates. Once you know what CD/DVD burning programs you have, go to Acer and download any updates (you can't go to the manufacturer of the program, because they make special editions for different computer manufactureres). If that doesn't fix the problem, you can find and reinstall your original program (you may have made copies of all your programs when you first bought your Acer). You can copy the original programs that came with the Acer using Acer eRecovery Management. (You can read about your Acer by clicking on "All Programs" and then on "AcerSystem", where you will find your manual, where you will find the following info: The eRecovery allows you to backup/restore the factory default image, and reinstall any applications and drivers. (In this instance you want to reinstall your CD-DVD burning programs). You just need to select the Burn Disc button, then select the application you want to burn to the disc--in this case, you CD-DVD buring program you identified with Belarc, burn it, then reinstall it. (You might want to burn all the applications the computer came with, just to have them for backup). That should get you going again. Let me know if you run into any problems.

Busco matshita dvd-ram uj-840s driver para el windows xp. Alguien me puede ayudar? No lo encuentro en ninguna pagina. En la pagina oficial solamente existe para el windows 2000. Gracias.


Not sure of your question; I read only English.

There are many sources for the drivers for your DVD; many would liek you to downlaod and use their driver update programs. An advantage is if there is ever an additional update the program will let you know. Here are two examples that you might consider as sources for an updated driver:

Drive cant write any disc


If the unit was working ok and suddenly the unit stop to read the blank disk, the problem could be related to a dirty lector (need to clean) or unit firmware (need to be updated)
In that case you can update your firmware here:

http://drivers.softpedia.com/progDownload/Matsushita-DVD-RAM-UJ-840S-104-Download-14615.html

***************************************************************************************
Remember

1) You have to use a blank "recordable disk" to allow your drive write a disk
2) Not all disks are compatible
3) Try differents brand
4) Clean your drive lector
5) Update your firmware

MY DVD DRIVE CAN NOT SEE VCD AND DVD THAT NEVER WRITE THEN CAN NOT WRITE ALL DISE BUT IT CAN READ VCD&DVD THAT EVER WRITTEN


you need to install a third party VCD viewer software...
some operating system doesn't come with VCD viewer.

when you look for a software you should keep in mind that you need a software that will support your dvd drive also.
