SDK / exoplayer

We've seen this issue reported three times now, so it's
obviously not an isolated problem. Do you think anything
bad will happen to non-SmoothStreaming playback cases if
I do this? I suspect not, but if you feel strongly I can
easily add a FLAG_WORKAROUND_X flag for it, and enable
it for SmoothStreaming only.
