Tested with sample from #695

Using ccextractor compiled from current master ( eb24e34 ) readded the Preview-section at the end of the log.
What information is it supposed to show?

C:\ccextractor-master\ccextractorwin.exe" -autoprogram -tverbose -out=srt -bom -
utf8 --nohtmlescape -o "Nurse Jackie".86.srt "Nurse Jackie.ts"

Min PTS = Max PTS and Length = 0?
That PTS-value is the first PTS of the Teletext-stream in the TS (PTS: 4778457019), the last being 14:45:06.926 or 4779623419.
