Description

Some DVB-S ts recordings (15 out of 56) contain DTS discontinuity errors, leading to playback problems (when skipping forward/backward). The beginning of one example is attached. In all but one case, the errors appear in recordings where EIT p/f was used.

Such ts recordings can be fixed with a post-processing script using a line like this:

ffmpeg -v fatal -probesize 500M -analyzeduration 1000M -i "$input" -map 0 -vcodec copy -acodec copy -sn "$output"

It would be ideal if anything inside TVH could prevent this from happening in the first place.
