I made a data dvd with Nero 6, and my Lite on DVDRW SHM-165H6S, firmware HSOE. Nero played the song saying that the burn was successful. Now the problem, if I put the dvd in my Lite on it will see all files I just burnt, but if put the dvd in my LG DVDrom GDR816B firmware OLO6, it only see there old files I previously burnt not the ones I just I added on. What’s up with this? 
Did some of my own searching and found that LG has firmware issues for this model. This has been an ongoing problem for LG since 2005. Picked up a new Lite on DVD ROM model LH 16DIP for under $20.00 Canadian, problem solved!! 
Glad to hear the problem resolved and thanks for posting the answer to the problem may become handy to some members facing similar problem…
