Seems like stream is broken. It should look like that:
Input #0, mpegts, from '/dev/dvb/adapter0/dvr0':

You have said it works some times. Could you try to using tzap + ffmpeg
cases when it works and when it does not. Use FTA channels to analyze as
I think ffmpeg could not say much about encrypted streams.
It's hard to say it works because I have no GUI on this PC and I don't
know a method to share directly device/stream into PC.
Hovewer I've tried to tune and analyze several FTA channels.
I have now better results because:
1) i've disconnected pctv device (USB & power)
2) poweroff
3) poweron
4) connect device
If I simply reboot or reconnect device - it doesn't help.

I don't know why it say device is in warm state. As I understand warm
means with firmware loaded(?), but this device was completely switched off.

I saved Mango file. VLC for windows doesn't play it, but Media Player
Classic plays it.
