 So I was watching a DVD (I've tested this on multiple DVDs and it's
 reproducible 100% of the time), ended up pausing it to make dinner. By the
 time I got back the DVD drive had spun down. I hit play and it played
 maybe 1/2 second and then hung while the drive spun up. Then it started
 playing and the audio was terribly desync'd from the video. I paused it
 then hit play. It helped. I did this a few times but the audio never
 sync'd 100% with the video. The log was spitting out the following:

 Eventually after enough pause/play sequences it stopped spitting that out.
 But the video was still off (slightly) from the audio.. then when it hit
 the next chapter I got this.

 Which repeated until I killed the frontend.
