Paul M I found that I could play live streams and recordings by side-loading VLC onto my quest 2. By using my alternative tvh_epg epg and channel listing web interface, I could download m3u files which vlc would open and then stream from tvh. Both dvb-s and s2 HD worked. https://www.reddit.com/r/OculusQuest/s/daMA3K0S5C
Paul M gah! I wish I'd known that in advance! well, it means I've got sidequest, f-droid, x-plore and vlc working well, so not entirely wasted.
