Hi, I also just purchased a Sony 700A, and I'd like to relay my experiences.
1) It installed great, and they have a great Nero package as said in the review.
2) I purchased Verbatim Datalife Plus 8X media. You are probably smiling now, since most of you know that this will only write at 4X on the drive (because of firmware issues). I didn't know that when I bought it though.
3) So I was trying to figure out why the drive didn't see it. After a few software updates to Nero and it still didn't work, I checked out Sony's site, and there it was (that it only writes to verbatim 8x media at 4X).
4) I didn't feel like returning it, so I did some web hunting. I found that the liteon 832s was the same drive, and that they released a firmware update in the beginning of June for the 832S drive. I downloaded it and of course it didn't work since it checks the current drive.
5) I found the hacked firmware (can't remember now where), that allows you to apply the firmware without it checking for current version. I was a little nervous since I didn't see anyone say that they have done this yet, but I tried it... and it worked...
6) I rebooted and ran Nero and saw that it can now write at 8X, however the Nero OEM edition won't write to the drive anymore, since it sees it as a liteon now!
7) The Nero Express part of the software for some reason still worked for me, and I was able to burn the 8X media at 8X, and no problem!
So now I have a Liteon Drive firmware in my Sony drive

in device manager it says:
LITE-ON DVDRW SOHW-832S .. and firmware VS03 (the sony came with VY02).
