Never. I'm not even a fan of digitally shot cinema, yet, or digital DLP's. When I really want to see a movie, or I've heard it has gorgeous cinematography; I want to watch a direct reprint of the master negative projected in film. It's still makes anything at home look like total dogshit, especially on a screen that large. Unfortunately, that's disappearing. Streaming video on the internet is of a particularly terrible quality. Yuck. No thanks.
The theater (cinema and dramatic) is still my church. There's an experience to be had there that can't be had at home.
