Hi guys,
The guys over at Zidoo have released a custom version of Kodi 15.2 (Final) for the Rockchip 3368 (Which the Himedia H8 is based). It's actually for the Ziddo X6 Pro box (Main competitor to the Himedia H8)
I've just installed it on my Himedia H8 and so far it works considerably better than the version of Kodi that comes with the 1.0.7 Firmware...

DTS-HD, TrueHD, DTS, Dolby Digital all pass through fine with no audio issues, They also pass in full 7.1.
PVR is back and working (With a few glitches but it's functional)
According to the Zidoo forum it can do frame packed 3D MVC although i haven't got anything to test it with on the H8.. 3D iso still pass through as SBS..
Here is a link to the file: https://www.dropbox.com/s/1pwqjkjfksvgcka/kodi-X6.apk?dl=0
You'll need to uninstall your current version of Kodi before installing this version on your H8. (Make sure you back up your settings.).
I haven't extensively tested it yet but it looks good, the only issue i have is that it's not recognizing my movie library. (But i'm working on that)
I'd be interested in finding out anyone else views.....

Mort..
