Seems like stream is broken. It should look like that:
Input #0, mpegts, from '/dev/dvb/adapter0/dvr0':
Duration: N/A, start: 19013.637311, bitrate: 15224 kb/s
Stream #0:0[0x231]: Audio: mp2, 48000 Hz, stereo, s16, 224 kb/s
Stream #0:1[0x131]: Video: mpeg2video (Main), yuv420p, 720x576 [SAR
64:45 DAR 16:9], 15000 kb/s, 26.89 fps, 25 tbr, 90k tbn, 50 tbc
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.
