It seems like an age since the last proper release of OpenPHT. I still use v1.9 embedded on my Wetek Hub on a daily basis and nothing else I have tried looks as good as the Black Edition skin.
Today the Raspberry Pi 4 was released with specs allowing for 4K HDR and DTS-HD/TrueHD/ATMOS passthrough.
It would be great to get an updated version of OpenPHT 2.0 Embedded for the Pi4
I have not seen much activity on OpenPHT 2.0 for a couple of years. I think the best bet is use LibreELEC which has Kodi and use the Plex plugin which works well even on my Pi 2. Sadly I now use Amazon FireStick 4k, Kodi method and modern TVs with 4k Plex app now. My Pi 2 is in the cupboard gathering dust. I do like the new Pi4 great specs, but too late for me to consider buying now.
