I have a number of DVDs that claim to have closed captions, but whose
display in MythTV is sporadic at best.  From what you're describing (all
caption text seems to be intact in the .srt file), it sounds like the
timecodes might be messed up in the original DVD MPEG source.  Do the
timecodes in your .srt file look reasonable?  I.e. the duration of each
subtitle, and the end time of one subtitle compared to the start time of
the next subtitle.

BTW, the closed captions are encoded as special packets in the MPEG file.
 It is up to the player to render them onto the video image and/or insert
them into the analog VBI output signal.  Only the former is possible when
using component or HDMI output.  MythTV has never done the latter, though
commercial DVD players probably do.
