A hard one. The file

/repository/UCLACorruption/2015-06-25_1800_US_KNBC_Access_Hollywood_Live.mpg

Produces some garbage under some conditions.

Report says that it happens with these parameters:

" 463 F=2015-06-25_1800_US_KNBC_Access_Hollywood_Live
464 cx=ccextractor-0.78-alpha1
466 $cx -ts -autoprogram -UCLA -12 -noru -out=ttxt -utf8 -unixts 0 -o $F.test2 $F.mpg

Note that the problem goes away if you use -1 instead of -12. It's looking for the second channel that triggers the junk inclusion, so it's finding this somehere."

To make it worse, it doesn't happen (to me) on Windows.

Output looks like this:

Can't reproduce with current git, so assumed fixed.
