What people are saying

Rated 1 out of 5 by from Not buying another LG Product! EVER I bought this unit a 3 weeks ago at Best Buy and it stopped reading blue ray discs (DVDs would still read. I tried calling Customer Support and got placed on hold many times during the call and was told that I could get a replacement reader and they would send me a email with instructions on where to send the player. The email NEVER came and when I called back I was told that supervisors weren't available until Monday, their email staff was off until Monday. YES... I looked at updating the firmware however your firmware patch was for 1.01 and the firmware on the reader was 1.02 so the patch wasn't even current. I wrote a previous complaint but it was deleted by LG so they don't like the truth being posted about their terrible product. Sorry but I'm a senior software engineer and not some non-technical purchaser. If this is how customer service works, I won't buy a product where I have to deal with LG again.

Rated 4 out of 5 by from software The player itself is convenient, easy to use. Te software (media suite) is very poor, customer assistance is non existent-every screen is promoting purchasing an upgrade -which is not what I expected when purchasing this unit---when i select an otion (such as burning a cd) the pop-up screen is so small I CANNOT READ IT EVEN WITH A MAGNIFYING GLASS. This limits the reason I purchased the unit---LG is great. Partners are not If viewing DVDs is reason for purchase, that seems to work well.

I bought this probably 2 years ago and within the last week it has stopped playing DVD's. It will play Blu-rays just fine. Not sure how to fix this. Anyone have any ideas?

Does this burner play pal or different region movies?

Asked by: natp
Our disc drives doesn’t follow regional code, as long as the media player software that you are using can play/read the disc from other region or can play PAL, then there should be any issue. ^AC

I have this blu-ray writer and I love it. Unfortunately I can't find the USB cable to connect to the computer. Does anyone know where can I get only the USB cable? Thanks.

Asked by: CarlosElCentro123
The cable you are looking for is called a USB 2.0 (Ytype). It contains both a micro-usb end as well as a mini-usb. There are many 3rd party vendor websites that sell this cable. ^CP

I lost the cable to connect the external drive to my computer, and I can't get my computer to recognize it. Can I use another Mini USB cable to connect it, or can I buy another cable from LG?

Asked by: Austin19
Hello, you can use another mini USB cable from any local electronic shops. Just make sure that it follows the same spec 2.0 to 2.0. ^AC
