It works ok. I used nero DVD copy on to a DVD+R, dont think it matters if + or -. Copy works fine, I can now keep the original safe. My version is 1.01 Oct 2000. Anyone know what the latest ver is?. When you ring Lexus, they do not seem to know, I always get "we will get you the most recent version sir". I got caught out by this before, ended up with 2 CDs the same for my LS400.
