Also Bug 908276 is necessary.

This issue also occurs on v1.2 Buri device. 
Playing the video from video app is not smooth.

We have tried base builds 0823 and 0815 by themselves, without additional builds on them, they worked fine with youtube videos.  We don't have base build 20130808 to test, which we think is possibly the cause of the issue. Between using base build 20130808 and 20130815 with moz builds on top, we noticed the youtube issue. 

Tested these on both 0823 and 0815 base builds -

Okay. Given Sotaro's comments, I think we know what we need to fix here to resolve this, so I'm pulling regression window wanted.

Yes, the problem could be fixed by Bug 907745 and Bug 901224.

Unable to repro on today's Buri 1.2 mozilla RIL.  YouTube videos play from beginning to end with no stuttering.  Resolving as Worksforme.
