Can someone please give me a straight answer on which Sony DVD-RW drive Lite-On has rebadged as the LDW-400D? I’ve heard it the Sony DW-U10A or another one but I hven’t heard anything definate. If it is one of these drives, can it still use the Sony firmware? Will using some particular firmware make any noticeable difference in performance/features (ie. get rid of the 2x DVD video read speed)? Can someone please answer these questions for me?

Thanx
