Despite having no idea what I'm doing that's never stopped me from blindly
rushing forward.

My bisect trials kept ending the same way with no conclusion so I took
another approach.

Looking at this page I narrowed down what I thought may be a range of
commits that could be causing the issue:

https://github.com/MythTV/mythtv/compare/fixes/0.27

I found on Aug 8 commit 6788ea9 was the last one that works for me.  I then
compiled the Aug 10 commit cb7fd95 and playback was broken.  It appears
everything on August 10th was reverts.  Could a revert of a previous patch
cause the issue?

This time I ran the bisect between 6788ea9 (good, August 8) and 082d5c1
(bad, August 10).  The bisect ended with:

commit f307a3d5e60b0054e1833127d417c6acfada3213
Author: Lawrence Rust <lvr at softsystem.co.uk>
Date:   Thu Jun 2 12:55:13 2011 +0200

    Player: Improve low bit rate / high latency stream playback

Which clearly shows I'm clueless on how bisect works as I tried to do it
between the commits on the 8th and 10th.  Again I had one bisect trial that
lead to a different playback behavior that was not good but a different
"bad" (no sound, choppy playback that corrected itself after several
seconds).

I'm at a loss!  At this point I think I'll stick with 6788ea9 until it's
resolved...
