i was reading about this player so just post some links - if you can read chinese http://www.hd.club.tw/thread-88926-1-1.html
it seems to be quite a player, has simple bd menu, among other things.

My friend got a 900B recently and we ripped a few of my 3D BDs to try out the player. It would play smoothly in the beginning but would show signs of instability after a while - we can't use FF or next, else the whole movie will stop and go back to the top menu, for some files, it will not be able to continue after playing for 10-20 minutes, then it just stops entirely.

There is also audio decoding issue - we just connected the player to Samsung 55D6400 3D TV (before that I connect the TV with HDXBD1, no problem producing sound when the audio is HD) - when the movie is on DTSMA - there is simply no sound (cannot downsample to DTS stereo may be?), have no chance to test TrueHD. The ripped discs are all in BDMV format, perhaps making it as ISO can help a bit?
