Rating: - Too Many Problems - Avoid This Drive
If you're building a new system, I recommend you consider another drive. This drive primarily has problems with Vista and new SATA controllers. I paired this up with a Asus microATX P5Q-EM motherboard with the latest firmware and drivers. The latest Lite-On firmware (CP56) didn't resolve any of the problems I had below.
(1) When Vista would wake from sleep, drive would be missing
(2) Drive would occasionally lock-up and make a "buzzing" sound when a Blu-ray disk was entered - this never happened with a standard DVD.
(3) Drive would occasionally lose power; could not ... Read More
Rating: - Good blu-ray drive; some problems and solutions
Summary: At time of writing, it is cheaper to install this drive in a reasonably powerful HTPC than to buy a blu-ray disc player, assuming you have the HTPC already. As with any new technology, there are problems; these will be worked out as the technology matures. You should upgrade the firmware (CP56 recommended). The bundled software, PowerDVD, has limitations and problems which you can work around.
NOTE: This drive is a READER only. It does not write any kind of disc. This is stated clearly in the product description and I am not complaining: it is much cheaper than a writer, ... Read More
Rating: - Blu-ray movies for a fractiont he cost
I bought this for my home theater PC so that I could watch blu-ray movies without having to buy a separate blu-ray unit or an HDMI switch. Unfortunately I needed a new video card in order to have enough power to watch blu-ray movies. The drive front bezel was too large to fit through the opening on my media PC case and the button placement was just enough off that the button placement on my media PC case doesn't actually hit the button. The bezel comes off so this was easily solved, though does leave me slightly concerned about getting dust into the drive. However once I had a suitably powerful ... Read More
Rating: - Great for its value
All my (only) three blu-ray discs played without problems (Blade Runner, Celine Dion and Shakira).
I took one star out of it, because it DID NOT read DUAL LAYER DVDs I have recorded here (from Ridata). Other DVDs and CDs media read normally.
I even updated its firmware to the latest version. But still didn't read my recorded DL DVDs. And... strangely, at Lite-On site, the firmware available for this drive says it DOES NOT read DVD-RAM also... as I don't have any media like that, I can't tell much...
But it is not a big problem, because in my computer I have a CD/DVD ... Read More
Rating: - Will not play Blu-Ray discs
Most reviews indicate that you need to upgrade the firmware.
I did this and still no Blu-Ray disc will play. Unable to read the disc.
PowerDVD advisor gives me all greens as to if my system can playback Blu-Ray, too.
Tested Blu-Ray disc by putting in a regular player, recognized and played just fine. There seems to be a problem with this particular model.
I went through 2 of them with the same results, will have to return the second one today.
Plays DVDs, but that's not what I bought it for.
Can't recommend buying this one.
