Sh1, Here is my case. I own a nh900 and a rh10. Both units are bought from HongKong sony store. The disc that I record from my nh900, it did not display correctly on my rh10. I am sure that my rh10 can display Chinese, as for the newly record disc from rh10 can display correctly. That is why I suspectly the encodeing problem. But in your case even it is the same nh1, but as you said they are from different country, 1 is japan, and 1 from China. I think for the Japan one, they will able to support Japanese, and English, but not other Language. For Sony to support Chinese they need to have a Chinese font include in the unit. So they may only include in the molde that need Chinese support in those countries. In return of Chinese support, we get a non-LCD display remote.
