Comment:

Could you upload a sample somewhere (around 50 MB if possible) that
illustrates the problem? I don't have access to teletext recordings, and
the handful of samples I have don't show the problem.

Comment (by Jason Lewis <jasonblewis@…>):

I cut out a bit of a video that shows the error several times.

Its about 51meg and still uploading to dropbox so give it a while before
trying to download it

Comment:

I have a fix that I'll commit to 0.25-fixes, but I'm setting the milestone
to 0.26 since we will probably be cutting the 0.25.1 release before the
fix gets enough testing in Master.
