Sure thing; glad to:
1. http://chapus.net/tmp/house-with-vbi-cc.txt
When I playback this recording, the Playback menu -> Subtitles sub-menu
gives me the option to choose between VBI CC or ATSC subtitles. When I
played this recording back I turned on VBI CC, which is what I normally
use (or used, since it doesn't work anymore). The above file contains
the stderr output from mythfrontend with -v playback,vbi.
2. http://chapus.net/tmp/two-and-a-half-men-atsc-cc.txt
When I playback this recording, the Playback menu -> Subtitles sub-menu,
only shows the ATSC Subtittles option. When I played this recording back
I turned on ATSC subtitles. The above file contains the stderr output
from mythfrontend with -v playback,vbi.
3. http://chapus.net/tmp/good-wife-atsc-cc.txt
When I playback this recording, the Playback menu -> Subtitles sub-menu,
only shows the ATSC Subtittles option. When I played this recording back
I turned on ATSC subtitles. The above file contains the stderr output
from mythfrontend with -v playback,vbi.
(3) is basically the same as (2). However, I decided to also play (3)
since that recording was done when I was running 0.23-fixes, and I am
pretty sure I was able to have both VBI and ATSC CC back then.
Do you see anything suspicious in these logs?

Yes, it is pretty weird since I am pretty sure I had working Closed
Captioning in some 0.24 release that I ran. I haven't downgraded but
I think I'll give that a try just to see if it's some change that was
introduced in 0.24-fixes. I saw your commits 27220 and 27124 in the
0.24-fixes changelog but I cannot see how these would have broken
anything.
Thanks in advance for taking a look.
Cheers,
Eloy Paris.-
