(From a different perspective).
I use to rip my blurays and watch the m2ts files on the computer. But I don't do this anymore. Too much work, for very little in return.
But with that being said, I primarily use my computer bluray-rom drive for checking all my newly purchased blurays for random bad sectors due to manufacturing defects + crappy quality control. If the bluray-rom drive encounters any bad sectors on a particular movie bluray disc, I immediately return the disc to the store for an exchange (or a refund).
Presently I'm using an ASUS BC-12B1ST, which appears to be an LG rebadge. I use isopuzzle to rip an entire undecrypted bluray iso to the computer's hard drive. The presence of bad sectors will show up very quickly on isopuzzle, since isopuzzle will try to jump over the bad sectors.
In terms of rip times, a single-layer 25 gigabyte bluray disc only takes around 10 minutes to rip the entire iso. A double-layer 50 gigabyte bluray disc takes around 30 minutes to rip the entire iso. (These times are only for ripping the entire undecrypted iso).
