Yes, all works fine using those versions.  I too tried an early version back in Feb of v.5.  HDR did not work anymore.  I think they stopped using private API's and went with Windows HDR.  Mistake imo.  3D used to work too but only if you downgraded resolution from 2160p to 1080p in Windows and NCP before playback and had to switch it back again after.  It wouldn't do the switch on its own.  Another failure imo.  (((((IF))))) they would revert to how they passthrough HDR in v.3 and (((((IF))))) they would straighten out 3D starting with the direction they previously used and auto switched the resolution to 1080p when playback started and returned to 2160p when finished, DVDFAB Player v.5 could give PowerDVD a real run.  Until then, I wouldn't waste my time unless anyone else has more positive experiences which I have not witnessed.  I have seen the same complaints though promised to be passed on to devs.

I don't think downgrading KODI on top of v.18 or vice versa is a good idea.  I copy and rename my v.17.6 entire userdata folder from time to time (back up).  Then I installed v.18 from scratch and save and rename it too.  Switching between the two is just a matter of installing v.17.6 or v.18 downloading to the program files folder and applying the corresponding userdata folder and renaming correctly.

Epic failure by DVDFab if that's what they did. No wonder they are giving away free keys. Unless they retract, this will kill the product.

I need to think about my Kodi installation a little. The reality is that the only problem I have with v18 right now is launching DVDFab. I have zero issues with Kodi itself or with launching PDVD. I have exactly 6 4K HDR titles in the hard drive which need this option. Although that number will grow, I'm not sure right now it's worth the aggravation. 

Currently I need to close Kodi, launch DVDFab and 'Open' the media -- which is a horrible HTPC experience. But for 6 or so titles, I think I'll wait a tad. Downgrading to v17 doesn't make sense to me for this. (At the moment). 

Thanks.
