I have always wondered what the TV stations use for source material. Well, during one of RTN's broadcasts, they transmitted the DVD menu for the program they were about to air. (see pic below) I have also noticed that Star TV Network uses a Sony DVD/Tape combo machine. (sorry no captures of this one) They also had up for a while an error message of no appropriate codec for the show they were transmitting. So I would have to say, they don't always use the high end commercial equipement, but the eveyday consumer stuff from their local discount department store.
