It looks like the code in textsubtitleparser.cpp thinks that we've hit
the end of the video.  It executes this code:

endCode = startCode + INT_MAX;
(http://svn.mythtv.org/trac/browser/trunk/mythtv/libs/libmythtv/textsubtitleparser.cpp#L85)

This seems to happen when two subtitles in a SRT file are very close
to each other (in my test case, about 0.205 seconds).

I'm not sure if this means this problem is on its own, or if it is
indeed related to the bitmapped subtitle issues.
