Crashes and 'slow mo' video going from 0407 to 0429 (Issue appears to be there on 0408 and above)

Unfortunately builds were down for a week when this issue started and quite a lot changed in the interval.
I'm not suffering from this issue and there weren't any pi specific video changes in this interval so I don't really have an idea about this.

All I can think of doing is randomly picking commits that appeared in the downtime and reverting them. If you spot a build where the problem is resolved let us know.
The next build will revert "VideoPlayer: do not render video until a/v streams are in sync". If no one speaks up I'll drop the revert in future builds and try reverting something else.
(unfortunately some commits have subsequent dependent commits which may make this hard to do, but hopefully one of the simpler ones will be responsible). 

@popcornmix , @Milhouse - Reporting on 0502 (RPI)

Good news is that 0502 appears to have solved the juddering. However it crashes..

I have a smartlist attached to favorites. When I select the video from the list, then I get the (waiting) wheel, and it then crashes/restarts - http://ix.io/19jC  (Let me know if you need a debug log as well)

If I select the same file, through 'file manager', then it starts and plays without juddering just fine.
Not sure if the change you made would have any impact/cause the crash, may be unrelated, but I am back to 0407
