Correct firmware updates

I have a Lite-on SHW-160P6S with a firmware version of PGS1. This is a Gateway firmware version, I believe. Per Gateway, there is no updated firmware for this burner. Yet, when I punch in the 160P6S for firmware updates, I see plenty, the latest being PSOB. I can’t believe there is no updated firmware for this model as I bought it almost a year ago. My question is: can i update my burner with the lates firmware I find on sites like “the firmware page” or do I wait for Gateway to come up with an update?? This burner works very well, thank you, especially with Ty02 and I know not if an update is even worth it. However, I wonder how one resolves Gateway updates with regular updates.
