People are choosing convenience over quality. I went to online-only with Netflix when they announced they were increasing the prices a while back. And Netflix has had pretty decent HD quality and DD 5.1 on some stuff for a while now.
I tell myself to use Redbox more often too.. (especially with this blu-ray burner I have... wink)
Yeah, my problem with Netflix is I'd have to relocate my router to get the bandwidth for HD. But the reason I never stick with Netflix is they don't stream hardly any movies I want to watch. Their new PS3 interface is awful, as well.
