HDMI Converters/Adapters?

I just got a PS3 (very nice) and we got the HDMI cable and all that jazz. Anyway, the HDTV we have in the den is about, i dont know, 3 years old maybe? It goes all the way up to 1080p so i figured it would have an HDMI hook up...i was wrong so i've only been able to play in 480i.

So this leads to my question, is there a converter or anything of the sort that can go from something like S-Video (i think thats what its called, if not, whatever it is)(It doesnt have to be S-video it was just an example so you know what im tryin to say) to HDMI?

Thanks in advance. Any help is appreciated. Please let me see what my PS3 can really do.

Yoo bro what it does!

emm my HD TV is also 3 years old, have my resolution in 1080i. I dont use S-Video, but I do use DVI. There is such thing as a HDMI - DVI cable/converter, because my TV is old and doesn't support it. Maybe you also have DVI, because if you do then there is a converter for you :) but if not, im not sure bout S-Video. And there is no difference from HDMI - HDMI and HDMI - DVI incase you were gonna ask, just different cables

Thank you so much man. Seriously. Thanks.
