Question: Does this unit have CINAVIA built in?
Document: had the same burner for two years and it worked great, built a new system and wanted the same burner, LG is a great product, will buy again !
This is a well-built product. The burner works great and the read mode is not too loud. Burns a 25GB blank in 25 minutes at 4X, takes 10 minutes to read it all back at maximum speed. No coasters so far. The tray mechanism is very smooth and whirry, which really adds to the quality feel.
Unfortunately I didn't discover the problem unit it was too late to return.
So far i have had no problems with this unit.Have not burned any &#34;coasters..I am very satisfied with this product
So Far I have burne about 3 BluRay disc and this unit is very fast. I bought it to do a lot of data backups and it has not disappointed me.
Unit generally works as expected. However, it occasionally is unable to read some DVD-Video discs, whereas other DVD burners can read those same discs.
I'm not using this drive for burning just yet. I'm ripping my Blu collection to my harddrive and using Handbrake to compress them to ~4GB files for my XBMC media server. In the past I used my laptops built in blu-ray reader to rip the disks, but it was locked at 2X and it took over an hour to rip a disk. I had to change something so I bought this and put it in my HTPC.WOW. I ripped a 22 GB blu using MakeMKV in 9 minutes.
I purchased this to replace a failed external bluray burner, it has exceeded my expectations. The unit is quiet, and fast during testing it actually performed better then the specs stated! I have yet to have a coaster from a simple backup, and I do more data backups then the normal consumer.
This unit seems to work fine in general.However, the unit has a contoured eject button - which means it doesn't work with my tower CPU case.My CPU case has an external button designed to contact a standard eject button - so, if your tower has a similar design this unit may not work once it is installed.
Very good product. Four stars is due to no software provided although its not needed. Company support is good and updates are available. This unit is fast and can burn many different disk types besides BD. As internal burners go, it is quiet and operates smoothly. I would buy another one if needed.
Answer: CINAVIA is a form of copy protection that basically determines if you are playing an invalid copy of a Blu-ray, and about 20 minutes into the film, it mutes the sound and puts a message on the screen that says "Don't adjust your volume. The audio has been silenced because Cinavia has determined that your disc is not authorized" (read: it's a copy, software .iso etc.)In the Blu-ray hardware market, stand-alone players and Sony PlayStations seem to periodically upgrade their firmware. Once you reach a certain firmware version, Cinavia is there to stay. Some work-arounds are available, but if you want to play your disks on stand-alone players, buy the disk. Also, many Sony Pictures Studios contain Cinavia, but it still remains relatively uncommon in the Blu-ray market in general (~less than 30% market saturation).One other notable option is to use any of the "Blu-ray/DVD Backup Utilities." One of these guarantees that any disk made using its software will (I can confirm this) play on any Software-Based Blu-ray player.I'm not taking any sides on the "intellectual property" issue. I'm just answering a question that was asked by a fellow Amazon shopper. Good luck, all.
