That nightly is the 11/14 or 11/15 nightly. My tablet died and I got busy with an emergency right now so I don't know what nightly I have on my nexus 7 but was able to use video add ons before with no issue. The program NaviX was force closing on me when I picked a play list. I get the messages that addons are incompatible, do you want to disable them, I choose no and they still work fine.
