Firmware

Hello,
I was wondering if the newest firmware version (v5S54) for the lite on 24x works the best or not? If not which one does? Thanks!

The 5s54 version seems to be the best for me, compared to the others:

-No clicks in sound when shifting zones anymore(did sometimes happen before).
-Better media compatibility, but some brands is now limited to lower write speeds since they sometimes failed at 20X and 24X writing.
-Better read quality, but a bit slower at skipping errors in cloneCD, not much slower though.
