First off, apologies if I picked the wrong area for this topic. Mods, please feel free to move this to a more correct location if one exists.
I had the opportunity to burn a Ultra HD Blu-ray movie on a 100GB BD XL BD-R disc a while back. I wanted to see what would happen when I tried to play the disc on a stand-alone UHD Blu-ray player. I remember there being some discussion more than a year ago about whether UHD Blu-ray disc format is the same as BD XL.
I can now attest that they are not the same format. I tested the disc on two stand-alone players, and both nibbled on the disc for maybe half a minute before spitting it out with an error message about unreadable media (or something to that effect anyway).
I’d be interested to hear from someone who has actual knowledge about the differences between these two disc formats. Anyone?
