I found gamecube games to look slightly muddy when playing with S-Video cables (yes I know I'm retarded..... should be using component). Other than that though, no problem with refresh rate/ghosting.
Get yourself some digital cable + hdtv only channels (HDFOX, HDCBS, etc.) and watch a football game!!
(btw, for any canadians out there, futureshop/rogers had a promotion running where if you bought any hdtv you would get a free subscription to digital cable and HDchannels for 12 months)
Great buy
!
(I really couldn't decide on what setting looked better though.... vibrant, standard or pro)
