I think this poster is implying the TV has only composite and s-video inputs. However, this idea of connecting through the DVD player will only work if the DVD player has an HDMI input. (if there's only one HDMI connector on the player, it's more likely an output). Now that I look, I'm having trouble finding hdmi to s-video or composite converters; it's easier to find one that converts the other way.
mle867, Is the HDMI the only video output on your laptop, and are composite and s-video the only inputs on your TV?
