Yeah, your player and TV should both at least have component connectors. Those are going to be vastly better than using composite/RCA. And while I'm sure there are "adapters" out there that you're looking for it wouldn't really provide much benefit. Hook it up with component video that'll give you much better results than composite.
There aren't any adapters that could take an hdmi signal, convert it to something composite rca would understand and retain the quality. RCA composite simply couldn't handle it.
