CCExtractor 0.77 and git-677fee4
File: http://www.mediafire.com/download/lzruvndz9mzoxul/dvb_not_found.7z (26MB)

The dvb-stream isn't detected, while extracting the teletext-subtitles works.
With 0.77 the program produces an empty SRT-file.

This is beta software. Report issues to carlos at ccextractor org...

But with the compiled git-version, the program crashes at the OCR-stage:

\src\lib_ccx\ocr.c
Line: 134

Run-Time Check Failure #3 - The variable 'end_y' is being used without being initialized.
