While waiting for a Netflix application upgrade to include a Browse or Search function, I've been using TiVo Search to find Netflix content outside of my Instant Queue. Since Netflix searching is mostly what I do in TiVo Search, I consistently have to reset my "A" options to the following:
Quality - HD only
Source - Watch now
Cost - Free only
Category - Movies (All) or TV (All)
It would be nice if TiVo Search allowed the ability to save those options as Default options for every TiVo Search session.
