[QUESTION] what's the problem with my raw 708 data from vanc? (No captions were found in input.)

[emcodem]

CCExtractor version: Version: 0.93

• Is this a regression (i.e. did it work before)? {NO}
• What platform did you use? {Window}
• What were the used arguments? ccextractorwinfull.exe -608 -in=raw C:\temp\vanc.bin -o c:\temp\out.srt

Additional information

This is a raw dump of ancillary packets recorded from Blackmagic Decklink SDI, the captions were inserted by FAB subtitler.
When i feed it to ccextractor, the stuff seems to be autodetected as 608 instead of 708, also i get "No captions were found in input" but the debug log shows someting at least.
For example (from 608 debug):

~- ~Ch~ar~ma~nt~e ~Un~te~rt~it~ezzzQengA?t^@f
PAC: 16 69  --  Position: 8:0, color: red,  font: underlined

The part "Charmante Untertite" is actually one part of the subtitles i was looking for.
Is this a problem with the data format of my raw file or more like missing functionality in the 608/708 decoders?
