W.r.t. to tuning I have the following recommendations
Change
detect_method=127
to
detect_method=63
as Silence detection only makes things worse for these recordings where there is no reliable logo
Change
min_show_segment_length=125
to
min_show_segment_length=250
as there are commercials segments as long as 162 seconds and any value of min_show_segment_length lower than 162 will force them towards show
You may decide to change
disable_heuristics=4
to
disable_heuristics=20
to disable heuristics rule 5 as it may wrongly delete a small show part after the last commercial.
Hope this helps
