Hi Alex,

I just wanted to thank you for taking the time to create the ticket for this problem:
http://code.mythtv.org/trac/ticket/9829
Then testing the patches from Gregorio. And Of course, I'd like to thank Gregorio for coming up with the solution.

One question for Alex, have the patches restored your ability to see CCs on your DVD rips?

FWIW, I've managed to backport Gregorio's fixes from both master and the patches associated with this ticket, to 0.23.1 (mythtv_0.23.1+fixes26863) and they've solved my problems with CCs. If anyone else is having problems with CCs on standard definition digital recordings, wants to stick with 0.23.1, and is comfortable building debian/ubuntu packages from source, I can probably put together a patch. Just let me know.

Regards,
Helen
