I was planning to use a TV card in the Mediator to view 15KHz screenmodes in a window on the Voodoo. Any idea how well this works?
It works pretty well. Even HW hitting games work, as long as you initialize the tvout before lauching the game (this might be a bit tricky to get working right, WHDLoad might work pretty well here).
There has been lots of discussion about this, for example
this thread.
PS. I've only seen it in action, I haven't actually built such system myself.
