I've hooked up my 57" widescreen, which should be similar.
I just use the S-Video out on my video card to hook it up, and it works like a charm.
My DVD player hooks up via S-video, so I just grab the cable from the back of it, and plug it into the computer.
When the computer fires up, the driver software detects the TV, and sets itself accordingly.
I really don't like playing on the bigscreen though because you can't see the whole playing field at a glance, like you can in a cabinet.
You have to move your eyes to see everything, which slows your reaction times.
