HIMEDIA with strengths in this segment should play HD quality play the file output 4K, 3D, Blu-ray, ISO than with other devices.

Agree. Just wish they would do a better job distinguishing between their various models, hardware revisions and firmwares. Also, an official English forum would help.

Couple of additional notes about Q5 as I play with it more...

• I do now notice (very) slight frame speed-ups occasionally, but not always when watching movies. Maybe due to lack of 23.976. I have my Chromebox packed up to eBay, but haven't quite pulled the trigger yet (may just keep it for a while, along with my RPi2). RPi2's development is going great, but there are some issues with crashes, certain live mpeg2 1080i stuttering, and no 3D ISO yet
  
• Although streaming apps like Netflix, Amazon, etc. sideloaded work, video isn't smooth
  
• Thought Q5 was supposed to have 8GB storage for apps? When I look under Android settings, shows only 2GB. So, I removed XBMC 13, which comes pre-installed with 1.0.7 Futeko firmware and other apps I was testing and only have latest Kodi 14.2. No performance issues yet though with my library of 1500+ movies and 50+ TV shows
  
• Tried Nova launcher, which seemed to work at first, but caused Kodi to break. Had to restore box via 1.0.7 Futeko firmware
  
• I do have Kodi now auto-launching via XBMC Launcher. Steps below...
  
• Still need to test VC-1 and non film-based videos (like concerts)
  

Steps for launching directly to Kodi on Q5 4K (English version):

1. Update to v1.0.7 firmware (as instructed here)
   
2. Install Kodi apk and launch it, then exit
   
3. Apply HiMediaWrapper APK (as instructed here)
   
4. Install update patch for Dolby ATMOS (as instructed here)
   
5. [Optional] Remove Kodi 13 from Android settings
   
6. Install XBMC Launcher (linked above; download via this). Open it and confirm Kodi is selected under 'XBMC variant', then exit
   
7. Power off Q5 until front panel light is red, then press power again. You'll be prompted as to which launcher you want; I selected 'XBMC Launcher' and 'Always'
   
8. Q5 will now boot straight into Kodi. When done using, simply press power on HiMedia remote
   

One issue with above is now that I have XBMC Launcher as my default launcher, I have no way to get back to Q5's settings or Android settings.
Solved: Under Add-ons > Programs > Android Programs, add 'Settings' and 'Launcher' as favorites so you can get to them from Kodi.
