I've just set up tvheadend for the first time, summary below:
On Raspberry Pi 4B 8GB with Raspberry OS Bullseye.
Using Hauppage dual tuner
Accessing New Zealand terrestrial Freeview
The issue I have is that the EPG is not fully populated, in fact is very sparse (many programmes are displayed but most without any descriptive info at all). All channels show something some time, but programmes appear at times then disappear. Playback of all channels works perfectly.
Could anyone please provide pointers on how to debug? I see nothing of relevance in the log. Also, when the tuner is plugged in to my windows pc the EPG is fine.
