"Neues vom Wixxer" (which is a bad German pun on the Edgar Wallace novel "Again The Ringer" ("Neues vom Hexer")) has been announced as the (allegedly) first Blu-ray Disc title to use the picture-in-picture feature of BD 1.1+.

See the (German) news article at Heise for a hires screenshot of the director's and actor's video commentary.

Hooray! So am I right in thinking there is one 1.1 profile player currently in existence? The Panasonic BD30, which, as of the discs release on Monday, is not yet available in Europe? Great work yet again from the BDA, every single manager and executive who is responsible for the farce that currently is Blu Ray deserves to be fired.
