Like others I was having trouble getting consistent 1080p/24 out of TiVo Netflix and suffered through resolution changes a lot. Today in my Netflix account I discovered under my account settings->Manage video quality none of the 3 options was selected (options are good, better, best). So I enabled "best" quality and lo and behold I watched 5 episodes of Breaking Bad without being interrupted by resolution changes. Playback now starts at 720p and then quickly goes to 1080p/24 and stays there for duration. So either it's a big coincidence that things got better or that setting actually does something to help TiVo Netflix.
