Comment (by bib1963):

 Here's another log when running "mythfrontend -v all".

 It's showing a 24m30s video ripped from a dvd.

 At the time I am running 'make MAKE="make -j4"' on a linux kernel build.

 This is on a 2c4t i3-4160 CPU @ 3.60GHz.

 Less than 3 minutes into it, audio sync was lost, with audio always ahead
 of video.

 The more concurrent jobs on the linux kernel build, the worse and quicker
 the sync loss.

 Even if you then kill the linux build, the video never catches up with the
 audio.

 It only seemed to start when the hardware interlacing was pulled into
 master.
