Yea, very annoying, you have to remux every one of you DVD's to .mkv first, and still, you have to switch the frequency manually for proper playback.
KODI is not an option, it doesn't switches freque either and does very lame deinterlacing compared to HiPlayer.
If there would any another Android Player app that could do this properly (I would even need the DVD menu, only the playback) it could be easily set up for KODI to playback only the DVD's.
I don't thing it would be so hard to implement by HiMedia, it's just that they don't even give dime...
