Comment (by stichnot):
A few observations so far.
1. Mostly (but not entirely), the garbling is because roughly half the
characters aren't being displayed.
2. xine shows almost exactly the same garbled captions as MythTV.
3. As noted, ccextractor (version 0.65 in my case) produces very clean
captions.
4. If you combine the captions from fields 0 and 1 by setting field=0 at
the beginning of CC608Decoder::FormatCCField(), most (but not all) of the
caption characters are correctly displayed.
Especially in light of the xine behavior, I suspect an upstream ffmpeg
problem, though it's also possible that it's a problem in our
avformatdecoder.cpp.
