Comment:
Reopening as there is still a problem with the sample referenced in the
ticket.
I have noticed similar issues with Live TV, and they may very well have
been fixed by recent changes. However, the colbertclip.mpg sample still
shows a ridiculously large duration. Most likely there has been a
regression in ffmpeg. Running mythffmpeg on the sample:

But running an older version of ffmpeg that happens to be installed:

Initial analysis shows that AvFormatDecoder::OpenFile() calls
av_estimate_timings() which calls estimate_timings() which calls
estimate_timings_from_pts(). That presumably fails because the duration
ends up AV_NOPTS_VALUE, which is translated as a ridiculously large
duration in the progress bar.
