Thanks for your reply. I don't have this model, I first saw this in a Western Marketing Store but didn't get the chance to try it out (busy store nung December). I Googled for Konka and saw your post, hence my request.
Yesterday I returned to the Western shop and managed to convince the sales guy to install the XBMC apk. The app installed OK, this is significant, since other Android-capable TVs like TCL can only install apps from Google Play (not from USB or other file storage medium). I then tried playing video files (1080p) from an external hard drive using XBMC but observed stuttering and jerky playback. This seems like a hardware limitation. Tried playing the files using the built-in media player of the TV and it played OK (observed no sound output for DTS files though).
I'm presently looking for an Android TV with an adequate XBMC performance. Complicating the scenario is that XBMC development is still ongoing for the Android platform (which is why the apk can only be downloaded from their site at the moment, and not at Google Play). Maybe I'll just get one of those Android TV boxes (or USB dongles). Or I can just wait for a good TV to come along (with hardware capable of rendering a high-definition file using XBMC), or for XBMC to be finalized on the Android platform :-)
You might want to confirm the CPU, RAM etc specs of your TV by installing the CPU-Z app from Google Play. The sales guy I talked to told me the RAM is 400-something (sorry forgot the exact value). You can just uninstall the app afterwards once you have confirmed the specs. Just my two cents.
