Today I tried to boot from usb ssd, I still get continuity counter errors in tvh if I playback an ongoing recording.
Are you recording to this SSD?
I saw this behaviour, but I haven't had time to look into it properly.
I've just done a very quick test with an SD TV channel. I started recording, and then started playing the recording. No errors within about a minute.
I record to a NAS which is connected to my raspberry pi 4 via a wired network.
Also, I was doing the playback on a different system to the one on which TVH is running.
I THINK when I saw these problems previously, that I was recording to the microSD card.
If your TV tuner is USB, and your SSD is USB, could it be that recording from one USB device to another AND playing the file back from USB is simply too much? Sure, it shouldn't reach the theoretical bandwidth, but you never know.
I guess it would be useful to know which scenarios cause the problem and which do not.
