here is the arguments
./ccextractor -quant 2 -in=ts -datapid 0x4db -out=srt -stdout -nobom -trim -noteletext -codec dvbsub -dvblang fra -ocrlang fra ./merged/c8.ts

and the result is:

I've included tracesports.ts which has 6 languages and cannot get the the Romanian language but it is there however I can get the pngs. Similar result with Chinese language also in tracesports.ts

The issue does happen but something weird I noticed about the subtitles is that they appear with a lot of noise and three instances appear on the screen at the same time. This could mean there might be some issues with the bundled closed captions of these transport streams.
