I tried it on my Ubuntu PC yesterday. PPS and PPLive seems to work. Chinese characters display is working well in default skin in Kodi nightly.
The CNTV add-on didn't work. The CCTV channels would all hang on "Waiting".
All of the CNTV regional channels report "No HLS Stream available". I wonder why? Is the CNTV add-on compatible with Kodi nightly build?
I installed nightly through the Ubuntu PPA:
sudo add-apt-repository ppa:team-xbmc/xbmc-nightly
sudo apt-get update
sudo apt-get install kodi
