Is this your first time trying to use the JVC/TY BDR media with your drive? If so, it looks as if TYG-BD-Y05 is not supported by your drive, just by looking at various PDF files covering support for this 6x media and the older 4x variant; in either case, support looks to be lacking in LG drives until the 10x models. Maybe a firmware update will help, but the drive is a little old, while the disc model is fairly new.

If it worked before but doesn’t work now, then something else is at work here.
