Install the latest beta and had no problem with m2ts and iso format. It's a much better player than xtreamer (1st version) as it can stream through network without stutter (it show 100mbps which shouold be good for any blu-ray ISO).Another plus is 3D blu-ray support. Still need some polish on the firmware as the interface is quite plain.
Problem now is everytime it try to access online video, it automatically download previous stable version.
