When I set th VAAPI playback profile in the setup wizard and attempted to
play the Big Buck Bunny sample, myth frontend just crashes. There was no
error message in the mythfrontend log. This was on an SD video as well, not
even the HD one in the wizard. On a previous install it would do the same,
crash the frontend, but the audio would be playing.  I have since blown
away that install and replaced it with this current one (mythbuntu 16.04
beta 1).

I needed to use the beta because the version of kernel in prior releases
doesn't support the Intel Braswell architecture. First attempt was with a
Xubuntu 15.10 with manual upgrade to kernel 4.4. The 16.04 beta 1 has that
kernel already.

If I had to guess, I would say the issue is with the intel graphics
driver.  If there is anything you would like me to try, I would be glad to
try to reproduce and see if I can get any log info to share.
