I was down at Future Shop here in Vancouver ( Canada, of course ) and had a look at
some of these new HP machines. I opened the tray on these optical drives, and it sure looks
like the familiar LG-ish belt-pulley tray mechanism. Yet, the bezel does not look like anything
produced by LG or Hitachi for that matter. These are probably the restricted/limited LG drives
designed to use only +R/RW media. So, I would assume these are the TRUE OEM LG drives
that LG warns in their firmware update instructions NOT to flash their firmware to.
I would think you probably need to change the booktype on those disks in order to play
on older stand-alone players, and better yet, use quality media. LG likes only quality media.
like Maxell and Fuji branded Richoh and TaiyoYuden, or MCC.
