Unfortunately there are no updates available for the UJ-8xx series (except for Sony - which won't work on other machines) as it just uses an old generic Windows optical device driver.
Your problems lie elsewhere.
These units have very very very strong region restriction - no reported patches or fixes that I can find...
So they come with an original region (the local one for where you bought the laptop) set by the manufacturer. You only have 5 possible region changes before it locks on to the final region permanently*.
There is very little info on the Matsushita (now Panasonic) website - but it appears that when you insert a different region disk into the drive it will automatically change the region restriction setting to that new region (and there goes one of your 5 allowed changes??).
If this is correct then you may start with for example a region 2 restriction (whatever the local region is for your computer) and record various DVDs in region 2 format. Then one day you try (deliberately or accidentally) a region 4 disk. Your drive reads it and changes the default to ... region 4 (using one allowed change)... next you put in one of your old disks - and the drive restriction default is changed back to region 2 (using another of your 5 changes) - until you've used up the 5 changes - when it's locked.
Because it's an odd number, chances are you'll end up with a permanent non-local region restriction...
* and Panasonic/Matsushita will only change it for a cost apparently...
so not very good news...
To help you, try this handy little free tool. It will tell you whether your drive is restricted, which region it's currently set to; and how many changes of the 5 you've already used:
now if I could just find out how to change the current region...

well all you need to do is put the disc in and go to whatever dvd you wanna burn. Click on it and then up at the top it should say burn xxxx

i,m assuming this is A laptop Computer ?
The only thing you can try is this:-
go to My Computer/Control Panel/ System/Device Manager.
see if there are any yellow triangles or exclamation marks by your problem device. if so click un-install. then at the top of that page, there is a refresh icon or similar. which will rescan the systems bus.
failing this try add new hardware wizard, in control panel.
finally ensure the device is connected correctly, unlock/remove and re-insert. update any device drivers for this.

Please read this post.
it has the same cd drive which you are talking about. the problem is only with the drive. they also do not provide any firmware to update it. there is no filters problem. the problem is mechanical which is something you cant fix. these are chinese made drives, just use and throw. so, its now time to throw. there is no point banging your head, becasue i already banged a lot for this issue, and please dont replace your drive with sony optirac, it will also give you the same problem. all the best.
the drive which you talked about is the same i had originally on my computer. i also tried myself to update the firmware of the drive but no go. it still did not work. so i checked the functionality of the dvd drive. what is the technology of dvd drive and i found there are 2 lenses in the drive to read cd and dvd. if one fails it will read only 1 type of cd or dvd then. presently my computer has 33rd optical drive which is again matishta. it is still working, i dont know how long will it work. but touchwood its working now. so all i can say after such a bad experience is that its just a luck. regarding which optical drive to get now? you can get any one. its just the name, technology remains the same. like a lot of different people. but blood remains the same. so name doesnot matter. But i strongly say drives with SONY OPTIRAC are the worst drive, Never buy that. other than that you can get anyone. hardly matters.
