Lite-On has done another update on their site, making available three new firmwares, WS05 for LTR-40125W, VS06 for LTR-48125W and 8S03 for LXR-24101A.
The VS06 has already been tested by our Lite-On Forum Moderator OC-Freak and it seems that is gives slower writespeeds but supports more media at 48X. Also SMART-BURN can't be completely switched off anymore.
Downloads of the new firmware can be found here.
