To resolve this problem, remove the affected filter drivers. To do this, follow these steps:
1. Click Start
Start button, type regedit in the Start Search box, and then click regedit in the Programs list.
If you are prompted for an administrator password or confirmation, type your password, or click Continue.
2. Locate, and then click the following registry subkey:
Caution There can be many instances of the registry subkey that is mentioned in step 2. You must make sure that you are in the appropriate registry subkey before modifying the UpperFilters and the LowerFilters values. To verify that you are in the appropriate registry subkey, make sure that the Default data value is DVD/CD-ROM and the Class data value is CDROM.
3. In the right pane, right-click UpperFilters, and then click Delete.
4. Click Yes to confirm the removal of the UpperFilters registry entry.
5. In the right pane, right-click LowerFilters, and then click Delete.
6. Click Yes to confirm the removal of the LowerFilters registry entry.
7. Exit Registry Editor, and then restart the computer.
The system will automatically rebuild the registry records when you restart your computer. Hope this helps.

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...
