Hi, sorry if this has been asked before. Im thinking of buying the EyeTV EZ so that I can play my Gamecube on my Mac (20" iMac G5, 2ghz, 512mb RAM). I know that it will work with gamecube (PAL) using the red,white,yellow cable (sorry, don't know the name), but im wondering about the lag. Apparentley there is none, but im sure that even half a second would be noticable when playing video games. Also, im wondering if it is compatible with 60Hz games, or if it just excepts 50Hz? This is an important aspect for me and will decided whether i buy it or not. thanks in advance for any help/info.
