I had been using openvix for years.
Your plugins won't work on zgemma using openvix. You can flash it ok then FTP anything into box.
Changed to openatv just the last few days and have taken to it.
Just don't like when a scan is in process it flicks over to the radio channel.
(doesn't happen on openvix)
so any recording will be interrupted during the scan.
I also added kodi direct to box. Great the way you can add streams into your bouquets so all your films are just 2 taps of the remote away.
