yes. The flash support is still not available which is a drawback for watching online movies. But i haven't yet experienced any out of buffer memory issue you mentioned for any of the applications. I am a regular user of almost all the applications you listed. Is it some kind of lag or tv itself restarts? As a suggestion, for watching online movies, you may screen share the notebook screen using widi or Miracast. Hope LG comes up with a firmware update (as they stated before) to fix the issue. Cheers :)
