Red_bird_2d_f3 ?????

[puschmannn]

hello together, please help me.
first, i´m puzzled by the name of my bluray: RED_BIRD_2D_F3
the movie is: avatar.
is it original? answer: of course, i bought it via amazon and it should be. but why is this name displayed?

why am i even asking this - because all other movies do work and my former power dvd(with my lg drive) and my tmt5 (trial) do play this movie very poor(lags or stutters on many places if this is correct english).

when i find a softwareplayer who is capable of playing it, i will buy it.
my system:

asus P8P67 pro rev 3.1
nvidia gforce gtx 560 ti amp!
8 gig ram(kingston)
i7 2600K quad @ 3.4 ghz
win7home 64 bit
drive: HL-DT-ST BD-RE BH10LS30 from LG (is this the problem? gg)

help!! i just want to play my avatar correctly!

greetings from austria,
markus

p.s.: there is no "austria" icon, so i took our great brother germany
