Use HDMI Switcher... it has multiple HDMI ports...

If your TV has a USB input, you can use a Roku Streaming Stick. Otherwise, you can use an HDMI Switch Box that allows you to connect multiple HDMI devices to 1 HDMI port.

Get an HDMI splitter which will allow you to use more than one cable

Not that I have seen but you can log on to roku.com and check with customer service, good luck.

Under the Internation option, there are free channels to subscribe. I'm not sure if there is a channel, but I did see channels like Malayalam, Bangla, Cantonese, Mandarin as well as others.

I got into the System Settings of my Roku3.
There are only 4 choices for Language:
English
Deutsh
Espanol
Francais

I'm not sure if it has a Chinese character option. However, the icon based channel panel is large and adheres to the channel's trademark for easy surfing. If the user is familiar with the channel at all it would be impossible to mistake the History Channel with Netflix.

I'm not sure but all you need to use it is the internet so I don't see why it wouldn't work in China, you can check with their customer support though, just to be sure.

It does not look like any of the ROKU devices officialy support anything over 110v, so you may need to get a new power supply or a step down transformer for it. On some user forums I did see some people say they had tried it on 220 and it worked.

Also, to connect to streaming services outside of china you would likely need to set up a VPN on your router since most subscription services require you to be in the USA.

I am not sure...I have heard that China restricts/blocks internet access to many internet sites so its quite likely that you would be unable to get to much if any of the content.
However, this is just my guess as I do not live in China so possibly my assumption is incorrect. This is just my best guess.

You could buy it here and use in China as the power for the device is USB.

It sounds like you need to upgrade your internet service to a faster speed.

Ck your internet speed provided by yr isp. If its less then 5 mbs, netflix will hicup.

Poor Internet connection. Are you wireless? If so, see if you can connect your netflix player with a hard wired network connection. If that is poor also, have you tried resetting (power off 15 sec) all your devices, and restarting them? Have you run an internet speed test using a home computer, or your smart phone when this happens? (search speedtest on google, watch out for adds though)
Do you have others sharing the internet at the same time? you need a minimum of 3mbs download to have a consistent Netlfix experience.

Yes, its a channel you just select and add to your channel list

Great choice and so many features that no other can provide

Not that I know of, but if you go on line or know of any such channels you can go onto the Roku web site and ask customer support

Under the Internation option, there are free channels to subscribe. I'm not sure if there is a channel, but I did see one that was listed as Arabic TV.
