Sony Drive & Nero 6.6 not "talking"



I recently purchased Nero v. 6.6 and am running it on a Win2000 machine along w/ a Sony DW-U18A DVD burner. Just tried my first burn tonight and it failed several times w/ several different media. I’ve since scoured the web and noticed that Nero has problems talking to this drive and it was recommended that I reflash the firmware to a Lite-On drive which Nero recognizes. I haven’t had any luck getting my hands on the firmware, so I thought I’d stop in here and see if anyone could lend a hand. Any help would be greatly appreciated.
