These only appear when jumping through the recording, not when playing.
They also appear in the backend log, when it is commflagging.

In the meantime, I found out that my recordings are OK. I have ber of
0-10 and unc of 0. ProjectX does not find errors in the files.
Since ffplay prints the same error messages when jumping, I guess it's
an ffmpeg problem with MPEG-TS recordings.
A friend of mine with DVB-S sees the same thing.
