Help with an older setup

I have a 17-inch, mid-2009 MBP, running a core2duo and and NVIDIA GeForce 9400M. My MBP has a mini displayport and I have a mini displayport to DVI adaptor.

What I want to do is hook the MBP up to my 50 inch plasma TV which (surprisingly) does not have VGA or DVI input: it does have component and HDMI though. SO...

Are there any adapters out there that will allow this MBP to either go from 1) mini displayport to component/HDMI (with audio) or 2) DVI (which I get from my mini displayport to DVI adapter) to component/HDMI (with audio)?

Thanks for any help.
