I have an LG CH08LS10 combo drive for maybe a couple of months now, but had not used it since now. I just rented a couple of blurays from the local store, and I am not able to reproduce them. In PowerDVD 10, I get the error "not-compatible disc detected in drive F" or something.
It is probably not a hardware problem, since I can use DVDFab to rip the bluray to my hard disk, so the drive can actually read the disc. I suppose it is a software problem - or maybe a codec problem. I tried a couple of free bluray players available on-line, but had no luck. I have the Shark007 codec pack installed already.
