I've been getting the same thing.  0.14 built from source,
MPEG4 capture, 4400 bitrate, AMD2500+ cpu,
about 10% capture, 4% playback, and it jumps.  I set
the video to the reference timebase, and it just makes 
everyone sound funny now once in a while, but at least it
doesn't freeze up now.  Seems like this has been getting worse
and worse.  I started at 0.10, which was absolutely flawless 
on this hardware, and it's been steadily getting more jerky with
each release.  I don't think my hardware is to blame, as nothing
has changed since the 0.10 install, just the mythtv builds.

YMMV,
