I believe that the FX 5200 Cinema Edition that he is talking about is about $60 - 80 bucks US dollars... Isn't that about 52 - 67 euros over there nowadays? I don't keep track with currency conversions... Personally, I use a Pinnacle PCTV for my video capture (my computer has cable TV and a PS2 hooked into it through that) which works extremely well for me. The resolution on it obviously isn't as good as a normal television, and capturing (recording) with a high level of resolution can make your computer run SLOWLY... If your computer isn't top-notch, that is.
By the way, I didn't understand your first question correctly I don't think... You meant for playing your PS2 on your computer instead of a TV, right? Sorry, I thought you meant for data transfer or something random like that... and if it so happens that you did in fact mean that, then the X-Port is still the only way that I know of.
By the way, xx cobra xx, besides the above connections mentioned, what are the other possible ones? I'm interested now... Sorry, but I didn't know there were other things you could do with it!
