I would probly think they were very blury.
Probly crud graphics just as they would be on a PS2.
I really cannot sit and play a PS2 because of the graphics its really slow and jerky,and the game programmers try to use a trail technique to fade out the all the bumps,of course it hardly works and gives the screen a cloudy affect.
Xbox graphics on a tele are not bad,but everything is out of proportion,and sound doesn't go in time with the picture.
You can indeed plug a S-Video cable from your TV-out port to your tele and see the screen as normal,but like i said it will probly be blury.
I prefer classical CRT's to TFT because they have a more colourfull picture,although to be honest the TFT's give a crisper picture.

Just imagine those big Rome Total War battles on a Digital projector,huh? ;-)
