I don't think anybody told you the faults of directv, so I'm confused. Secondly, you asked for suggestions pertaining to four different categories. I don't really have suggestions on a larger tv, jensen stereo, nor speakers, but I did take time to respond to you on the dish equipment that works great for my family.
