H-L (Hitachi-LG) BU40N BU50N are claimed (by their sellers) and look like being upgrades of LG BU20N Blu-ray disc drive.
Are they compatible? Thanks
If it isnt on the list, they either aren't compatible, or more likely, no one has tested. As far as I know, im the only person who has ever tested with a BU20N drive, and it works very well.
