Hi,
Is this firmware link an update for my UJ-820D dvd burner to a double layer burner?
As i waited alot of time to see this to happend... 
Almost certainly not. As far as I know an upgrade like that isn't possible, but I might be wrong.
I just tried it myself since I have the same drive, but in true Sony style they haven't provided a readme, so I have no idea what the update does, if anything.
Dual layer is a joke guys, the disks cost a fortune.
But yes you are right Pixeldude, firmware can allow for DL writing, not sure that revision can.
Would ask VAIO Link
Really? Firmware can do that? Go firmware!
I suspect they would have said if it did, although not telling you what it does is annoyingly poor practice.
Yeah I have seen it on some of the Sony laptops....
Think it was the S series...

Yeah the only thing you can do is hope somone has done the update and posts here.
Or VL get back in touch soon
Its pretty much for double layer support the firmware
i will update it soon as i finish to reinstall my windows..
and i will post here 
Good luck
I also have the UJ-820D dvd/rw drive but in my A115M.
I was hoping the firmware update was to fix an 4x speed dvd-r write issue. I can only write max 2x speed.
However, after updating the firmware I can still only write to dvd-r at max 2x and my eject button has stopped working.
Also the volume buttons, screen zoom button, brightness button and s1 button no longer work either.
Thanks Sony for messing up by beloved notebook even more.
I hope other users do not suffer the same problems as me.
