I used this guy's script (https://github.com/ItsDeidara/DNSwitch) with an Apache server running on Ubuntu.
It does the exact same thing in TV mode. I haven't tried lower res. video's yet though.
I've been playing Killer Clowns from Outer Space all day, is pretty fun. Basically Friday 13th but with clowns. One of my favorite b rated movies from way back.
