Ah; here's a comment on a different matter from Neil Wilkes:
"...a written disc is technically not a BluRay disc, and no players are actually required to play them at all.
This is why duplicated discs should not ever carry the BluRay logo (they are, to use Sony's terminology, "non compliant products" as they are BD-ROM finalized as BDMV)
Only replicated (pressed) discs can be guaranteed compliant - and even then, some players will not play all discs."
His comment re BDMV is the relevant part. You can see that "BDMV, BD-R" is what is being displayed instead of the title and a "disk" rather than the thumbnail. Two possibiities. One is that the BDMV nature of the disk does not provide what is needed. The other is that it is possible, but if it is, Encore provides no direct way to access it.
