Some SONY drives are actually made by LiteOn.

That drive is listed as a 16x dual layer drive. I don't see why you would need to update anything. Have you actually tried burning a disc in it?

Not all discs are compatable with all drives unfortunately, so there is a bit of trial and error there as well. Hopefully these will work just fine.

http://forum.rpc1.org/dl_result.php?kaj=1&iscesI have the same Sony DVD writer & also I just bought Maxell 16X DVD-RW's. My DVD writer keeps asking me to insert a recordable disk ie. it does not want to accept these 16x DVD-R discs when I try to burn to it. I called Future Shop to ask what the PROBLEM could be & I was told that my Sony writer needs replacing. I told him the writer works fine with 8X's DVD_R discs. He told me it's just a matter of time before it won't work with the 8X's DVDs either. I also tried Memorex 16X DVD-RW's with the same RESULT. The next problem I noticed was that my Sony DVD writer  was also having trouble PLAYING back recorded DVD's ie. sound was garbled & video would momentarily freeze up. Ended up replacing the Sony DVD writer.

My conclusion is that 16X DVD's should work with the Sony DW-D22A without any firmware upgrade. I just had the unfortunate coincidence that I was trying new 16X's DVDs at the same time my burner started to break down.
