I want to use Comcast's HDTV service with my NEC VT540 front lcd
projector but I cant because Comcast's box only has composite video
out and the projector
only has rgb in through a monitor type plug.  Does anyone know what I
can use to convert between the type of composite video that Comcast
uses and type of input that my NEC VT540 projector has.  I was looking
to spend at most around $300.  I would like to output from the
projector a 1021i(?) image.

When I typed 1021i I meant 1080i.

Hello and thank you for your question.

Google has a new service, under the clever name "Froogle"
www.froogle.google.com

I believe I have located the product you need, at prices as low as
$97.99.
"composite to rgb" 
http://froogle.google.com/froogle?q=+%22composite+to+rgb%22+&price1=&price2=300&price=between&btnP=Go
"VB50-HRTV"
http://froogle.google.com/froogle?q=VB50-HRTV+&btnG=Froogle+Search

According to its specifications, the Viewsonic VB50-HRTV TV Tuner
Module will accept a composite video input, and will output an rgb
signal.

Thanks again for giving me the chance to track this down for you.
