Limitations of using a Japanese Blu-ray Recorder in the US?

[rlove2u]

Hi all,
I have been researching the Japanese Blu-ray recorders. And have finally found a source to get one thru. But I am still trying to pin down the compatability issues with using it here in the US. It is my understanding that now that Japan is in the A/1 region same as US and Canada there will be no issues playing region 1 DVD's, or A/1 BD disks. Also Japan is on a 100V 50hz
power grid. I have confirmed that this unit will work properly on any power
grid from 100-240 at 50/60Hz. I have also confirmed that Japan/Asia are on the PAL broadcast system, where we here are on the NTSC system. But I have been told that that difference will only affect terrestial broadcast signals only. That satellite signals will be uneffected ex.Dish DirecTv etc.
Can anyone confirm this?? Or offer any thoughts? Also I don't know if this unit offers any other language besides Japanese, since they are only sold in Japan. I know the onboard TV guide within the BW900 would probably be wasted. And that the remote would be in Japanses but I have a learning remote so that won't matter. Let me know if anyone has any thoughts.
