Actually, I think Blig may have just managed to come up with the first coherent method of getting table-top dice based rp onto a tv screen without taking away the table-top dice based nature of the thing or turning it into either a drama or a sit-com.
DM and group of players on the one side of things, playing a normal game (within pre-selected parameters). On the other side of things, after the game's over, you have actors/cgi/whatever acting out the game 'as it happened'. Edit down to 45 mins to an hour, place on bbc 2 either just after or just before Time Commanders.
...I'm not sure that this is a good thing, however.
