MATSHITA DVD +- RW UJ 857G Driver Problem/Solution

I have DELL XPS 1330 with MATSHITA DVD UJ 857G DVD Drive. Because of nVidia problems, the mother board is replaced three times (thanks GOD that I took 3 years warranty on it), so I didnt pay a single penny so far on repairs.
Now I formatted it with Vista Ultimate 64bit and later I found that Vista is not detecting drivers for DVD.
I searched a lot but didnt find any suitable driver.
In device manager for the drive, I was getting error 32, and googled it based on the error description,and then I found the following posting:

It talks about error 39, still I did the same what the post says... and deleted entry LowerFilters - PxHlpa64. Restarted the computer, and noticed that drive is working just fine.
